The discography of Hüsker Dü, an American punk rock band, consists of six studio albums, two live albums, one compilation album, two extended plays, and ten singles.
 The band was formed by Bob Mould (guitar, vocals), Grant Hart (drums, vocals), and Greg Norton (bass guitar) in 1979.
 Their first album release was "Land Speed Record", a live album released through New Alliance Records.
 The band released its first studio album, "Everything Falls Apart" on its own label (Reflex Records) the following year.
 Hüsker Dü signed with SST Records in 1983, and released its next three albums with that label.
 The Warner Music Group released the band's last two studio albums.
 Hüsker Dü broke up in 1987.
 The band released 5 albums, including two double albums, between January 1984 and January 1987.
Hüsker Dü was an American rock band formed in Saint Paul, Minnesota, in 1979.
 The band's continual members were guitarist/vocalist Bob Mould, bassist Greg Norton, and drummer/vocalist Grant Hart.
 Hüsker Dü first gained notability as a hardcore punk band, later crossing over into alternative rock.
 Mould and Hart were the principal songwriters for Hüsker Dü, with Hart's higher-pitched vocals and Mould's baritone taking the lead in alternating songs.
Jay's Longhorn Bar, most frequently referred to by patrons as The Longhorn, was a nexus of the punk music scene in Minneapolis, Minnesota, in the late 1970s and early 1980s, described by music critics as a "legendary" part of the genre's history and a "punk rocker's paradise."
 One of the earliest clubs in America to regularly book punk, New Wave, and alternative-rock bands, the Longhorn was the only concert stage in Minnesota where touring acts in those genres could regularly perform until the opening of what would become First Avenue in 1980. "
The Police, Blondie, all the big acts played there," wrote Hüsker Dü guitarist Bob Mould, who frequented the venue and noted that he considered Hüsker Dü "an actual band" only after they had performed on the Longhorn stage.
 Robert Wilkinson, singer for Minneapolis punk band Flamingo, noted that in terms of importance to the scene, “The Longhorn was Minneapolis’ CBGB’s.”
Circle of Friends is a DVD by Bob Mould of a live concert recorded in 2005 at the in Washington, D.C.
 The performance included songs from Mould's earlier bands Hüsker Dü and Sugar, as well as his solo work.
 This particular show was part of the "Body of Song" tour, Mould's first non-solo tour for over a decade and the first one in which Hüsker Dü material was played in a band format since the band broke up in 1988.
"Don't Want to Know If You Are Lonely" is a song by Hüsker Dü from their album "Candy Apple Grey".
 The song was written by Grant Hart.
 It was released both as an EP in the United States and as a single in the United Kingdom in March 1986.
 Hüsker Dü filmed a promotional video for the song, which garnered the band some play on MTV.
Warehouse: Songs and Stories (1987) is the sixth and final studio album by alternative rock band Hüsker Dü, originally released by Warner Bros.
 Records as a double album on two vinyl LPs.
 The band dissolved following the tour in support of its release, in part due to disagreements between songwriters Bob Mould and Grant Hart over the latter's drug use.
 This album, along with "Candy Apple Grey", showcases the increasing maturity of Mould and Hart's writing—a change which alienated some long-time fans.
 This album is also known for its battle between the two songwriters, with Mould famously telling Hart that he would never have more than half of the songs on a Hüsker Dü album.
2541 is the first solo EP from Grant Hart, formerly of the band Hüsker Dü.
 It was Hart’s first solo release after the breakup of Hüsker Dü in January 1988 and was released as a 3-inch mini CD single and as 12-inch, 45 rpm vinyl single.
Gregory James Norton (born 13 March 1959) is an American musician, formerly of the band Hüsker Dü.
 While the majority of the band's songwriting was done by bandmates Bob Mould and Grant Hart, Norton contributed the songs "M.T.C.," "Don't Have a Life" and "Let's Go Die" to Hüsker Dü's debut EP "Land Speed Record".
 He was born in Davenport, Iowa.
Reflex Records was an American independent record label formed by the members of hardcore punk band Hüsker Dü and Terry Katzman.
 It was formed to help promote independent bands, after Twin/Tone Records rejected Hüsker Dü's first single in 1979.
