PRIVATE PARTY - "Katie, together with her piano and bass players, entertained at our West LA holiday party. Katie is warm, adorable and a wonderful talent. Her sidemen are serious, accomplished musicians. Having Katie Harris Jazz perform in our home is a reminder of the depth of talent we have in Southern California. She'd be a headliner working a regular gig in another part of the country. The guest list of was a sophisticated group of 90 that ranged in age from early mid 20s to 80,and included several entertainment moguls. Everyone loved the trio. If you like good jazz and fine musicianship and a cool vibe delivered with warmth, Katie Harris is for you." -Bruce S, Los Angeles, CA

We had special requests for our First Dance as well as the processional songs and they were very accommodating. Everything sounded perfect!

The even broke into some AC/DC during a jazz set late in the evening for a guest request! Our guests were incredibly impressed with their performance and many asked where we found them.

BIRTHDAY PARTY - “The Secret Jazz Band played during my husband’s surprise birthday dinner. I highly recommend this band. Five stars from all angles. Their being there took my soiree from being just another dinner all the way to « a truly elegant affair ». Seriously.

Katie (the super-talented vocalist) was the sweetest —from our very initial engagement to our last. She and her band members were early for set-up. Their calmness and confidence really helped put me at ease. Katie’s voice and her band members’ instrumentals were 10/10 flawless. They presented themselves professionally. Their breaks and exit were smooth and unnoticeable. The cake-cutting tune they played was most adorable — a sweet surprise that my husband and I recalled and sang again later LOL. So many of my guests complimented the band and asked how I found them. Literally everything was just above and beyond about The Secret Jazz Band.

100% recommend. They will exceed your expectations!” -Sasha M, Costa Mesa, CA

Besides that, Katie is such a sweet person! She was a breath of fresh air when everything around me was so hectic. It was such a pleasure to work with her!! She was always so quick to get back to me when I had questions and she bent over backwards to cater to my requests. She and her band truly set the perfect mood for my day" -Erin O, Trabuco Canyon, CA

CORPORATE EVENT - "Katie Harris and The Secret Jazz band played our corporate event with over a thousand people at the Westin Bonaventure LA in an atmosphere (noise level, traffic) that was sometimes challenging. We asked for a last minute change in location and they were very accommodating. They were all smiles, very professional and never got ruffled by anything. They brought all their own equipment and lights and performed at 100% percent. The music was awesome -- the playing and singing first-rate. I give them five stars all the way -- if you book them I bet you will not be disappointed." -Rob W, Los Angeles, CA

WEDDING - "Katie Harris & her quartet were amazing!! Words could not describe the romantic and exciting ambiance that they created with their performance at our wedding.

First of all, communication was excellent. Katie was always quick to respond, followed up, and answered all of our questions and concerns both in writing and in person.

“Amazing - We Highly Recommend Them”

The Secret Jazz Band played at our wedding and we all LOVED them. They played our first dance song live and NAILED it. I attend a lot of live music performances and I rate The Secret Jazz Band as a top notch band. Their talent is amazing as is their professionalism and communication. The ambiance they provided for our special evening will be forever foremost in our memories. Have I mentioned, I just couldn't stop dancing?! and our guests are still talking about "the band"! Our Day Of Planner has added them to her preferred vendor list. We took someone's advice in their review – “hire them and don’t look back” – and now I’m passing that advice to you too! -Review featured on WeddingWire

Renee & Luke

South Coast Winery ~ Temecula, CA

The Secret Jazz Band Featuring Katie Harris made my day so incredibly special. They were professional, on time, and prepared with the song selections and announcements. Having live music at the wedding made such a difference. As a surprise, our family members request they play a song for us. The band was more than accommodating and seemed thrilled to welcome the opportunity to play with more people. Katie sang beautifully and the other players did an incredible job. Even after lots of people had moved outside, the band continued to play and it was a great moment for us to sneak in another dance. They made my wedding the best day of my life. -Review featured on The Bash
