James Iha

Throughout their existence, the main focal point of The Smashing Pumpkins was undoubtedly singer/guitarist Billy Corgan -- due to the fact that he was the group's main songwriter, as well as his penchant for colorful quotes in interviews. But of course, there were other members of the band, and behind Corgan, the one who contributed the most in the songwriting department was guitarist/co-founding member James Iha.
