HEAR

Katy Perry Sure, Perry has an unprecedented run of infectious pop hits to play live, but the biggest draw might be her kaleidoscopic stage show, which includes a giant mechanical horse, an inflatable car and Perry dressed as a cat on top of a huge ball of yarn, among other, more understated elements. September 26, 7:30 p.m., $30-$154, MGM Grand Garden Arena.

Spellbound Expert vocalist Kristen Hertzenberg, formerly of Phantom—the Las Vegas Spectacular, returns to Cabaret Jazz with an eight-piece band for a “love-haunted” evening of blues, rock, jazz, folk and country. September 27, 5 & 8 p.m., $29-$45, Smith Center.

Ty Segall Whether you’ve caught him a half-dozen times or haven’t yet heard him in person, the California garage-rocker will remind you what you love about live music—even that buzzing in your ears in the next morning. With La Luz, Leather Lungs. September 28, 9 p.m., $10-$12, Beauty Bar.
