One by One is the fourth studio album by American rock band Foo Fighters, released on October 22, 2002 by RCA.
 The album is the first to feature guitarist Chris Shiflett.
 Production on the album was troubled, with initial recording sessions considered unsatisfying and raising tensions between the band members.
 They eventually decided to redo the album from scratch during a two-week period at frontman Dave Grohl's home studio in Alexandria, Virginia.
 The songs on the album, which include the successful singles "All My Life" and "Times Like These", have been noted for their introspective lyrics and a heavier and more aggressive sound compared to the band's earlier work, which Grohl said was intended to translate the energy of the Foo Fighters' live performances into a recording.
Wasting Light is the seventh studio album by American rock band Foo Fighters.
 It was released on April 12, 2011 on RCA Records, and is the first album to feature rhythm guitarist Pat Smear since "The Colour and the Shape" (1997), making the band a five piece with the album.
 Wishing to capture the essence of the group's earlier work and avoid the artificiality of digital recording, frontman Dave Grohl arranged for the band to record in his garage in Encino, California using only analog equipment.
 The sessions were supervised by producer Butch Vig, with whom Grohl had worked on Nirvana's "Nevermind".
 Since the old equipment did not allow for many mistakes to be corrected in post-production, the band spent three weeks rehearsing the songs, and Vig had to relearn outdated editing techniques.
 The band went for a heavier and rawer sound to contrast with the musical experiments from their previous albums, and most of the lyrics were written as Grohl reflected upon his life and possible future.
 Guest musicians include Bob Mould, Krist Novoselic, Jessy Greene, Rami Jaffe and Fee Waybill.
Foo Fighters is the self-titled debut studio album by American hard rock band Foo Fighters, released on July 4, 1995, by Capitol Records through Dave Grohl's label Roswell.
 Grohl wrote and recorded the entire album himself – with the exception of a guest guitar spot by Greg Dulli – with the assistance of producer Barrett Jones at Robert Lang Studios in Seattle, Washington, in 1994.
 Grohl claimed he recorded the album just for fun, describing it as a cathartic experience to recover from the death of his Nirvana lead singer Kurt Cobain.
Danny Robert Worsnop (born 4 September 1990) is a British musician, singer and songwriter, prominently known as the lead vocalist of rock bands Asking Alexandria and We Are Harlot.
 He has worked with several artists including I See Stars, With One Last Breath, Breathe Carolina and Memphis May Fire, providing guest vocals on several songs.
"These Days" is the third single, (fourth in the UK), from the American rock band Foo Fighters' seventh studio album "Wasting Light".
 It was written by Dave Grohl and co-produced by Butch Vig.
 Dave Grohl has stated that it is his favourite song that he has ever written.
 On August 18, 2012, the Foo Fighters performed "These Days" at Pukkelpop, as a tribute to the people who died or were injured there a year earlier, due to a violent thunderstorm that raged over the festival grounds.
Foo Fighters is an American alternative rock band, founded in 1994 by musician Dave Grohl.
 After recording by himself what would become the album Foo Fighters, Grohl decided to recruit a full band with him as singer and guitarist.
 The original line-up included bassist Nate Mendel, drummer William Goldsmith, and Pat Smear.
David Eric Grohl (born January 14, 1969) is an American rock musician, guitarist, singer, drummer, songwriter, record producer, and film director.
 He is the former drummer of the grunge band Nirvana and the frontman and founder of the rock band Foo Fighters, of which he is the lead vocalist, rhythm and lead guitarist, and primary songwriter.
Foo Fighters is an American alternative rock band formed by multi-instrumentalist and vocalist Dave Grohl in 1994.
 After recording the album "Foo Fighters" alone, Grohl enlisted guitarist Pat Smear, bassist Nate Mendel and drummer William Goldsmith to join the band.
 This lineup recorded the second Foo Fighters album, 1997's "The Colour and the Shape", although most of Goldsmith's drum recordings were removed and re-recorded by Grohl for the release, after he left the band due to creative tensions.
 Goldsmith was replaced by Taylor Hawkins, and Franz Stahl replaced Smear after he also departed, although he only remained in the band for a short period and did not record an album with the group.
 The group's third album, "There Is Nothing Left to Lose", featured Hawkins on drums and was released in 1999.
Songs from the Laundry Room is an EP by American rock band Foo Fighters, released exclusively for Record Store Day 2015.
 This EP and the Foo Fighters album are the two Foo Fighters releases upon which Dave Grohl plays all the instruments.
The Colour and the Shape is the second studio album by the American rock band Foo Fighters.
 Produced by Gil Norton, it was released through Capitol Records and the group's own Roswell Records on May 20, 1997.
 The record is the debut of the Foo Fighters as a group, as the band's previous record, "Foo Fighters" (1995), was primarily recorded by frontman Dave Grohl and friend Barrett Jones as a demo.
 After the project ballooned and became an international success, the group convened for pre-production in the fall of 1996 and brought in producer Norton to establish a pop sensibility for the tracks.
 The band strived to create a full-fledged rock record, although the music press predicted another grunge offshoot.
