A Few Reviews

"The Katie O'Brien Duo is the best duo ever! They both have such beautiful voices and are very talented. Their personalities shine so brightly. They are very professional and accommodating. We asked them last minute to shorten up a song and within minutes the song came out perfect. We couldn’t have asked for anything or anyone better! Everything flowed beyond perfectly. We can’t thank you enough for helping to make our wedding day the best day of our lives, for us, and all of our guests! We will definitely be passing your name along to anyone who’s in need of live music. Looking forward to hearing you again at our house warming party this fall! Thank you for the amazing job on our special day!"  --Ann-Marie & Mike

"We cannot thank you enough for making our big day so special. You sang our song 'I Choose You' (Sara Bareilles) better than the artist as Bonnie made her way down the aisle. Your powerful and beautiful voice is so well complemented by your guitarist. Together you made magic and set the tone for a wonderful day that we will always treasure. Do not hesitate to pass our contact information along should anyone be looking for a recommendation for their wedding or any other event."  --Paul & Bonnie

"Katie and the band were wonderful to work with, and they made our wedding ceremony and reception memorable and SO much fun! Communication was excellent leading up to our wedding, and they perfectly captured the vibe and style of music we envisioned for our big day. Everyone was on the dance floor all night, and we received endless compliments about the music in the days that followed.  I highly recommend hiring Katie for your next event!" --Tori P.

"There aren't enough positive words to describe how amazing the KTO Band was!! They absolutely smashed our wedding out of the park!! Our guests started dancing before the salads were served and didn't stop dancing until we actually had to add on more time.  Everyone commented how this was the best wedding they had EVER been to!! Music and food are the two most important things of a wedding and if you also want to have the most memorable wedding like ours look no further than the KTO Band! 


From the very beginning to after the wedding they were very attentive, quick to respond, understanding, and Katie has the most amazing pipes; they even sent photos & videos after the wedding so we could keep reliving it!

5 out of 5 stars" -- Elyssa B.

"KTO was FABULOUS! Every single member of the band was so talented and had fantastic energy. The band was super easy to work with, and they seamlessly incorporated our song requests and genre preferences. They played an incredibly diverse set and nailed each song.  Thank you guys for helping make our night so special - we absolutely recommend them to anyone looking for a wonderful live band!" -- Charlotte S.

"If you are in doubt of what is the most important element of a memorable wedding than let me tell you it is the entertainment.  We had a blast with the KTO Band all night long.  There was no dull moment.  Katie, Samuel and the entire band were outstanding and the music fantastic.  Having several musicians in our wedding group I kept hearing where did you get this band?!  We danced thru dinner and until the police showed up during the encore.  Their music is timeless, they are fun and professional, and what's most important-the music will always be the first thing mentioned as we remember this happy wedding day and how lucky we were to have the KTO Band there to celebrate with us.  Thank you!" -- Jill B.

"If you're looking for the right music for any occasion whether it be a wedding, corporate event, birthday party, anniversary or any celebration under the sun...then your only choice is KTO BAND. This is Katie O'Brien's band which means you'll get a vocal powerhouse when it comes to singing talent and an impeccable professional when it comes to planning each event. If all you need is a "cover band", you'll find thousands of them online all promising the same thing but if you want an ensemble of experienced musicians who will make your event a memorable one, go PRO and hire KTO. You'll be happy you did - and so will your guests!"

-- Carolyn

"The KTO wedding band is amazing. Very professional and top notch performance and production. You won't be disappointed. Super happy to work with Katie and her wedding band."

-- Lauren

"Amazing wedding band! Very professional, accommodating, and of course, talented! Katie and the whole crew really made our day so special we can’t thank or recommend them enough!" -- Kate

KTO performed at our wedding and I couldn't recommend them more! Katie, the band leader was professional and prompt, she made sure everything was arranged as we planned. The band played an amazing set that kept our guests dancing all night long, their energy and talent is amazing. Days after our wedding our guests were still telling us how much they loved KTO! -- Ron

Katie and the band did a fantastic job at our wedding! From booking, to working with Katie on our song preferences, through the actual event everything went flawlessly. The band Energized the event and kept everyone dancing. Our guests loved the live music and atmosphere.  -- Martina

“I met Katie O’Brien of the Katie O’Brien Duo when my wife and I were leaving Tremezzo Ristorante in Woburn after dinner. We heard an amazing voice and when we turned to listen, we decided to stay and hear more. We then went to see them a few weeks later – and at that moment, we decided to hire them to sing at my company’s holiday party. They were excellent! They showed up early, set up and put on an amazing show at the Fox and Hound Wood Grille and Tavern. Their performance was brilliant! Our employees requested songs and they played them all night long. The owner and staff at the restaurant enjoyed them so much, they want them back to play on weekends. If you’re thinking of hiring the Katie O’Brien Duo, just do it! You will not regret it. Thank you both for making our holiday party the best one ever!”  --Jim R.

"Ok--I admit it.  I am a Midwest wedding snob.  I am at the point in my life where I am either planning a child's wedding or attending a friends' child's wedding.  Pre-covid we logged 8-12 a year...usually all in the summer.  The wedding band can make up for not great food, bad weather or awkward table mates.  Nothing is greater than a wedding with a kick-ass band and tons of dancing!  Our son was getting married in New Hampshire.  Most of the guests are coming from the Midwest, and the Mother of the groom is ALL about the band!  I was nervous...I did not want a DJ, I wanted a extra horn and uplighting to warm the white tent.  Enter Cover Story Agency...Chris was our contact and he set us loose on the website...I was open minded...(remember though, I am a Midwest band snob).

And as if sent from the heavens...we saw the clip of Katie and Sam.  We were pretty pumped...she had some pipes on her that was even evident in the video.  Lots of planning...lots of songs to choose from...lots of discussions about the "feel and vibe" we were looking to create.  The list was made and fingers were crossed...Music at the ceremony was gentle and sweeping...beautiful.

And then it was time for the party!  From the first note of the wedding party introductions, to the end of the evening...the house was rocking!  These people are TOP-NOTCH PROFESSIONALS!  Seriously...EVERYONE was dancing, happy and joyful!  We actually had to ask people to stop in order to serve dinner.  They read the room with precision; the song list was varied and amazing!  Their energy and passion for what they do was off the charts!  They are the real deal--and that is coming from a self-professed Midwest Band Snob!

We did not want the evening to end and extended the party for another half hour.  No one left...the dance floor was packed!  I cannot say enough about the KTO Band!  If you are looking for a group to set your party in motion and send it soaring, they are it!  Katie has the voice of an angel and the band is in sync and raging with talent and precision.  OUTSTANDING!!  Luckily for us the weather was perfect, the food was excellent, and the band put this Midwest snob in her place...OVER THE MOON at her son's KICK ASS wedding!!"

-- Joanne B.

"The KTO Band made and I do mean MADE our wedding. They were easy to work with leading up to the event, nailed all the small stuff like intros and moving events along, and fully delivered with a great sound throughout the evening that kept the dance floor full and the energy high. I can’t recommend them enough for anyone looking for live music for a wedding or event." -- Ryan

"I first heard Katie at Hopothecary in N Reading. We could hear some of our favorite acoustic tunes being sung live in the other room so I made sure to follow up with a phone call to the brewery
the next day to find out who that awesome singer was - and learned it was Katie O'Brien. I checked out her website, saw that she's part of a full wedding band and hmmm. At the time, we were in the beginning stages of planning a 40th birthday party for a close family friend. He would tell me how great this band was that he'd been listening to on Friday nights at the Harbor Lounge at the Encore. Then the AHA was the KTO Wedding Band! I called Katie to speak with her about doing his private party (in our backyard) and despite the fact that she could have booked a wedding gig that August Saturday, she was extremely enthusiastic and accommodating. We wanted something a little more upbeat than the acoustic duo and Katie suggested we add a drummer to kick it up a bit, and the KTO Trio was born!

They were amazing- the sound, the music, the vibe all perfect.
And they can do everything from rap to country to pop, 80s, to latest top hits. Katie even helped by participating in the tributes. I can't say enough about how great the KTO Trio was.
They made a good party one everyone will remember.
A friend liked them so much she hired them to play at her Oktoberfest next month and I already have another idea for a gig next September. Thank you Katie & crew! See you soon."

-- Deb

You can’t go wrong with this group!! KTO played our wedding this past weekend and they were beyond our wildest expectations. This was a musicians’ wedding with plenty of critical ears in attendance - the band was by far the highlight of the night from everyone. They were extremely professional and played a wide range of music at a high level. Some wedding bands don’t rehearse/throw things together last minute - not this band. They were polished and it was evident that they play together regularly. Everyone was on the dance floor immediately, and stayed there all night. Stop searching and hire them - and add the horn section. It’s absolutely worth it. Thank you so much KTO!!  -- Sam

We hired KTO for our wedding band after receiving a recommendation from a friend. It was a second wedding for both of us and so it was an older group of guests. Surprisingly the dance floor was packed the entire time! The music was spectacular! We added a trumpet and sax to the base band of six members and highly recommend them all. Our guests were blown away as were we. Great event!  -- David
