CHAPEL HILL, NC—Angie Carlson, 22, girlfriend of AstroPuffs drummer Steve Molzen, encouraged him to sing on some of the band's songs Monday. "You have such an amazing voice—just because you're the drummer doesn't mean you can't sing, too," Carlson told Molzen after a gig. "Just look at Dave Grohl." Carlson went on to ask Molzen if there has ever been a band where the drum kit was positioned at the front of the stage.
