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.
Born James Yoshinobu Iha in Chicago, Illinois, on March 26, 1968, he found himself playing in several obscure local bands during the late '80s (including such names as the Feds and Snake Train), before meeting Corgan through a mutual friend in 1988. Playing its first few shows without the aid of drummer (a drum machine kept the rhythm), the duo eventually formed the Smashing Pumpkins, with D'Arcy Wretzky and Jimmy Chamberlin filling the bass and drum slots, respectively. Melding together psychedelia, alt-rock, and heavy metal, the group had a sound and look (thrift-store clothing) that was completely different from its competition at the time.
The band eventually signed on with the indie label Caroline and issued its debut full-length, Gish, in 1991, which included the Corgan/Iha co-penned highlight "I Am One." Touring alongside the Red Hot Chili Peppers and Pearl Jam, the Pumpkins were poised for a breakthrough with their next album, but inner-band turmoil almost split the band up. Despite the fact that Corgan supposedly played nearly all the instruments on 1993's Siamese Dream, the album catapulted the group to the top of the charts, and once more, Iha had co-penned some of the album's best tracks along with Corgan -- "Soma," "Mayonaise," and "Spaceboy" -- in addition to singing lead on a European B-side, "Blew Away" (the first song completely penned by Iha to appear on a Pumpkins release). Up next for Iha and his bandmates was a bombastic double album, 1995's Mellon Collie and the Infinite Sadness, which made the band one of the biggest rock acts on the planet, and included another tune sung and penned entirely by Iha, "Take Me Down." Iha and bandmate D'Arcy formed their own record label the following year, Scratchie Records, which over the years issued recordings by the likes of the Frogs, Fountains of Wayne, and the Sounds, among others.
In 1998, Iha found the time to issue his debut solo album, Let It Come Down. Somewhat of a departure from the alt-rock of the Smashing Pumpkins, the album revealed Iha to be a fan of '60s-influenced melodic folk-rock and '70s soft rock. Although it did not make a huge impact commercially, with its sweet romanticism and sunny melodies Let It Come Down developed a cult following over the years and established the aesthetic direction for much of the work Iha would involve himself in outside of the Pumpkins.
In 2009, Iha, along with Hanson's Taylor Hanson, Fountains of Wayne's Adam Schlesinger, and Cheap Trick's Bun E. Carlos, recorded and toured as the supergroup Tinted Windows. The band's debut album featured a melodic power pop sound that fit well with Iha's long-avowed love of '60s and '70s guitar pop.
