Reynolds was reluctant to become a professional musician, partly because of what future band member Wayne Sermon told him: "Don't do music because you want to do music--do music because you can't do anything else." After beginning school at Brigham Young University, Reynolds felt like no other career choice fit.
With Reynolds singing lead, Imagine Dragons won BYU’s "Battle of the Bands" and other local competitions. After relocating to Las Vegas, they caught their first big break when Train's frontman fell sick just prior to the Bite of Las Vegas Festival 2010. Imagine Dragons were called to fill in and performed to a crowd of more than 26,000 people.
Local accolades including "Best CD of 2011" (Las Vegas SEVEN Magazine), "Best Local Indie Band 2010" (Las Vegas Weekly), "Las Vegas' Newest Must See Live Act" (Las Vegas CityLife), Vegas Music Summit Headliner 2010, and more sent the band on a positive trajectory. They released their third EP, It's Time, in 2011.
