Goon Moon is an American rock band composed of Jeordie White (also known as Twiggy Ramirez) and Chris Goss.
 The band released the mini-LP "I Got a Brand New Egg Layin' Machine" in 2005 and have since recorded a full-length album, "Licker's Last Leg", which was released on May 8, 2007.
 The album features cameos from longtime Goss collaborators Josh Homme and Josh Freese, as well as desert rock mainstay Dave Catching.
 Although Goss and White continue to work on other projects, they have both alluded to the possibility of future Goon Moon recordings on Twitter.
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.
Socialism of the 21st century (Spanish: "Socialismo del siglo XXI" ) is a political term used to describe the interpretation of socialist principles advocated first by Heinz Dieterich in 1996 and later by Latin American leaders like Hugo Chávez of Venezuela, Rafael Correa of Ecuador, Evo Morales of Bolivia, and Luiz Inácio Lula da Silva of Brazil.
 Socialism of the 21st century argues that both free-market industrial capitalism and twentieth-century socialism have failed to solve urgent problems of humanity, like poverty, hunger, exploitation, economic oppression, sexism, racism, the destruction of natural resources, and the absence of a truly participative democracy.
 Therefore, because of the local unique historical conditions, socialism of the 21st century is often contrasted with previous applications of socialism in other countries and aims for a more decentralized and participatory planning process.
 Socialism of the 21st century has democratic socialist elements, but primarily resembles Marxist revisionism.
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.
Foo Fighters: Back and Forth is a 2011 rockumentary about the American rock band Foo Fighters, directed by filmmaker James Moll.
 The film documents the band's history, and gets its title from a track on the Foo Fighters' seventh studio album "Wasting Light".
Many science fiction works have been set in the 21st century (years 2001 to 2100).
 With humanity now in the 21st century, many of the predictions of these works have so far been proven obsolete.
 This page lists only "predictions" regarding the 21st century, as opposed to contemporary accounts of the actual 21st century, which would be too numerous to list.
Sunny Day Real Estate was an American emo band from Seattle, Washington.
 They were one of the early emo bands and helped establish the genre.
 In 1994, the band released their debut album "Diary" on Sub Pop Records to critical acclaim.
 However, shortly after releasing their second album "LP2", the band broke up, with members Nate Mendel and William Goldsmith joining Foo Fighters and Jeremy Enigk embarking on a solo career.
 In 1997, they regrouped long enough to record two more studio albums and a live album but ultimately disbanded once again in 2001.
 The band reunited again in 2009.
 Bassist Nate Mendel, who chose to remain with Foo Fighters during the previous reunion in 1997, took part in this reunion.
 In a 2013 interview with MusicRadar, Mendel said Sunny Day Real Estate was inactive.
 According to Mendel, the band attempted to record a full-length album after the end of their reunion tour, but the sessions "just fell apart".
 In 2014 the band released one song from those sessions, "Lipton Witch," on a split 7" vinyl with Circa Survive on Record Store Day.
Foo Fighters is an American rock band, formed in Seattle, Washington in 1994.
 It was founded by Nirvana drummer Dave Grohl as a one-man project following the dissolution of Nirvana after the death of Kurt Cobain.
 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".
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.
