Foo Fighters is an American rock band, formed in Seattle in 1994. It was founded by Nirvana drummer Dave Grohl as a one-man project following the death of Kurt Cobain and the resulting dissolution of his previous band. The group got its name from the UFOs and various aerial phenomena that were reported by Allied aircraft pilots in World War II, which were known collectively as foo fighters. Prior to the release of Foo Fighters' 1995 debut album Foo Fighters, which featured Grohl as the only official member, Grohl recruited bassist Nate Mendel and drummer William Goldsmith, both formerly of Sunny Day Real Estate, as well as Nirvana touring guitarist Pat Smear to complete the lineup. The band began with performances in Portland, Oregon. Goldsmith quit during the recording of the group's second album, The Colour and the Shape (1997), when most of the drum parts were re-recorded by Grohl himself. Smear's departure followed soon afterward. They were replaced by Taylor Hawkins and Franz Stahl, respectively, although Stahl was fired before the recording of the group's third album, There Is Nothing Left to Lose (1999). The band briefly continued as a trio until Chris Shiflett joined as the band's lead guitarist after the completion of There Is Nothing Left to Lose. The band released its fourth album, One by One, in 2002. The group followed that release with the two-disc In Your Honor (2005), which was split between acoustic songs and heavier material. Foo Fighters released its sixth album, Echoes, Silence, Patience & Grace, in 2007. In 2010, it was confirmed that Smear had officially rejoined the band after having toured with Foo Fighters as an unofficial member since 2005. Over the course of the band's career, four of its albums have won Grammy Awards for Best Rock Album. The band's seventh studio album, Wasting Light, produced by Butch Vig was released in 2011, in which Smear returned as a full member. As of 2015 the band's eight albums have sold 12 million copies in the US alone. The band's eighth studio album, Sonic Highways, and their second recorded with Butch Vig, was released in November 2014.
