Sometimes, it's hard to know what constitutes a band. Billy Corgan wrote and sang all the songs for The Smashing Pumkpins and still records under the name, even though the other original members are long gone. Same deal with James Mercer and The Shins.
Jason Lytle is the man behind the Modesto, Calif., band Grandaddy. The band released its debut in 1997, but it was Grandaddy's second album — The Sophtware Slump — that broke through with critics and fans. Even David Bowie called himself a fan when he approached the band members after seeing them play.
