Question: Who is an American musician, principally known for his work as guitarist, vocalist and songwriter for alternative rock bands Hüsker Dü in the 1980s and Sugar in the 1990s,  Amanda Wilkinson or Bob Mould ?
Context: Bob Mould (sometimes referred to as Hubcap) is the third solo album by former Hüsker Dü and Sugar guitarist and singer Bob Mould.  It was recorded and mixed between September & November 1995 and released in April 1996.  Mould played all of the instruments on the album himself, and the sleeve notes declare, "This one is for me."  In the place of traditional band credits, the sleeve states, "Bob Mould is Bob Mould." Robert Arthur Mould (born October 16, 1960) is an American musician, principally known for his work as guitarist, vocalist and songwriter for alternative rock bands Hüsker Dü in the 1980s and Sugar in the 1990s. 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. 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. 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.” Amanda Nicole Wilkinson is a Canadian country music singer.  She was born January 17, 1982, in Belleville, Ontario, Canada and was raised in nearby Trenton, Ontario. 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. Copper Blue is the debut studio album by American alternative rock band Sugar.  It was voted 1992 Album of the Year by the NME.  All of the songs were written by guitarist/vocalist Bob Mould, who also co-produced with Lou Giordano.  The song "The Slim" is about losing someone to AIDS.  Musically, the band continues the thick punk guitar of Mould's previous band, Hüsker Dü, while slowing the tempo and emphasizing melody even more. 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. 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.
