Although they evolved into a full-fledged pop band, Guster began their career as a quirky acoustic trio. The band, whose three co-founders met during freshmen year at Tufts University, spent most of the 1990s touring the college circuit and releasing independent albums, all of which featured hand percussion in lieu of a traditional drum set. Released in 1999, Lost and Gone Forever widened the band’s sound considerably, and the follow-up album found percussionist Brian Rosenworcel playing a drum set on several songs. Multi-instrumentalist Joe Pisapia joined the lineup in 2003, allowing Guster more freedom to explore a combination of folk, pop, and rock.

Guster formed in 1991, when Ryan Miller, Adam Gardner, and Brian Rosenworcel first crossed paths at college orientation. Originally called Gus, the trio played local shows around the Boston area before releasing an independent album, Losing Sleep, in 1994. By 1996, they’d elongated their name to Guster and recorded a second album, Goldfly, which netted the band a contract with Sire Records. Sire reissued Goldfly in 1998, and the bandmates decamped to a recording studio later that year to work with producer Steve Lillywhite. Released in 1999, "Long and Gone Forever" became the band’s unofficial breakthrough album, cracking the lower reaches of the Billboard charts and spinning off a hit single, “Fa Fa,” which peaked at number 26 on the Adult Top 40.

Compared to Guster's early albums, "Long and Gone Forever" was downright lush, with strings and horn sections beefing up the band's standard mix of bongos, vocal harmonies, and folk-pop songwriting. Guster went even further with their follow-up effort, Keep It Together, which featured drum kit percussion and contributions from a talented multi-instrumentalist named Joe Pisapia. The album was released during the summer of 2003, where it cracked the Top 40. Meanwhile, the band also released a “fake” version of the record, The Meowstro Sings -- Guster's Keep It Together, in which Guster’s vocal tracks were replaced with simulated cat meows. The so-called “meow mixes” were released online in an attempt to battle illegal file sharing.

Several months after Keep It Together’s release, Pisapia joined the group permanently. He made his official debut on the 2004 concert album Guster On Ice - Live From Portland, Maine, which found the guys playing selections from all of their albums. Now a four-piece outfit, Guster returned in 2006 with their richest-sounding album to date, Ganging Up on the Sun. The group's sixth studio album, Easy Wonderful, which was partially recorded in Pisapia's Middletree Studios in Nashville, was released in October of 2010. Right around that time Pisapia announced he wouldn't be touring with the band any longer, choosing instead to play with k.d. lang full-time. He was replaced in the touring lineup by guitarist Luke Reynolds, a former member of the band Blue Merle. ~ Andrew Leahey, Rovi
