[Crowd Theory] was such a pleasure to work with. They made everything so easy before the event. Then of course--the music itself was fantastic! It was a private work event and people were trying to pay money to come inside to participate because of how good the music was. I wouldn't hesitate again to have them at another event. Thanks you guys!

I was extremely pleased with my experience with Crowd Theory. I thought there were a fun, hip band--exactly what I wanted for my wedding. They upheld a sense of professionalism and tact every step of the way. They put together the perfect setlist, keeping things upbeat and fun. I know Crowd Theory will make your event perfect!
-Bethany S. (Wedding)
Extremely professional, easy to work with, friendly, and incredibly talented, Crowd/Theory is surely a band on the rise. Every email was answered very quickly, the band was very flexible (accepted the gig with 5 days' notice) and accommodating, and most importantly, their music was AWESOME!
