Guided by Voices (often abbreviated as GBV) is an American indie rock band formed in 1983 in Dayton, Ohio. It has made frequent personnel changes but always maintained the presence of principal songwriter Robert Pollard, who founded the group with guitarists Mitch Mitchell, Tobin Sprout, Jim Pollard, and drummer Kevin Fennell. The "classic" lineup included these musicians and bassist Greg Demos.
Noted at first for their lo-fi aesthetic and typically Portastudio four-tracks-to-cassette production methods, Guided by Voices' music was influenced by post–British Invasion garage rock, psychedelic rock, progressive rock, punk rock and post-punk. The band has had a prolific output, releasing 24 full-length albums along with many other releases. Most songs are in the two-minute range, but many are even shorter; often they end abruptly or are intertwined with odd and homemade sound effects.
Guided by Voices initially disbanded in 2004. In 2010 the "classic" lineup reunited to perform at Matador Records 21st anniversary party, subsequently touring and releasing six new albums. GBV broke up a second time in 2014, but Pollard again rebooted the band with a new album and a new lineup in 2016.
