Bob Schneider and Salim Nourallah

You may know Bob Schneider. And you may know Salim Nourallah. But you probably didn't know that the two Texas singer-songwriters are childhood friends who played together while growing up in El Paso. Most people would never put the pair in the same sentence: Schneider is the swaggering, perennially-almost-famous frat-boy rocker who once dated Sandra Bullock and makes a sport of sweeping Austin Music Awards; Nourallah is the impassioned but easygoing Dallas folk-pop singer behind this year's glittering gem of pop understatement, Polaroid. Their show at the Granada is the first time they've played together since high school, so we're hoping for a little duet action or, at the very least, some embarrassing high school anecdotes.
