Las Vegas may be best known for its flashy casinos, but its history of producing top-caliber rock acts is equally impressive. Imagine Dragons—dubbed one of 2012’s brightest new stars by Billboard magazine—is another Sin City success story. The band's grand, electronically embellished rock show will include its hit single “It’s Time” and other tracks from its first full-length album, Night Visions. Opening acts include Australian indie-rock band Atlas Genius and California rock outfit Nico Vega. Sat 7 p.m.
