[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 had the absolute best time at my wedding and Sean and [Crowd Theory] had a large part in making it the most memorable and best dance party of my entire life. I actually danced for two hours straight instead of talking to my guests and have zero regrets about it. They played such fun sets and had our guests on the dance floor the entire night. Even the catering gals were dancing in the kitchen to the songs! The level of talent and professionalism I got from Crowd Theory exceeded all of my high expectations and I want to get married at least every year just so I can have them back. On a logistical note, Sean was fantastic at communicating with me through the entire planning process. Crowd Theory definitely made my wedding and I could not be happier with them from start to finish."

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!
