Poison Years is a compilation album by Bob Mould, who had been the guitarist and co-vocalist of the influential American rock band Hüsker Dü.
 It is essentially a condensed version of Mould's first two solo albums on Virgin Records, "Workbook" (1989) and "Black Sheets of Rain" (1990), and was released in mid-1994 after Mould had achieved considerable success with his new band Sugar.
 It contains 6 (out of 11) studio tracks from "Black Sheets" and 5 (out of 11) tracks from "Workbook", of which 3 are previously unreleased live versions.
 In addition, the album contains a studio outtake from the "Workbook" period, "All Those People Know", a live version of another non-album track, "If You're True", and a live cover version of "Shoot Out The Lights" from the eponymous 1982 album by Richard and Linda Thompson.
Silver Age is the tenth solo album from former Hüsker Dü and Sugar frontman Bob Mould.
 Mould was joined on bass by Jason Narducy and on drums by Superchunk's Jon Wurster.
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.
Workbook is the 1989 debut solo album by American guitarist and singer Bob Mould, following the breakup of the influential rock band Hüsker Dü.
 The album has a strong folk influence and lighter overall sound than he had been known for up to that point, although heavy guitar still features occasionally.
 Drummer Anton Fier and bassist Tony Maimone, both of Pere Ubu fame, served as Mould's rhythm section on the album and on the subsequent live shows.
 The single "See a Little Light" was a hit on the US Modern Rock chart.
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.
Before Their Eyes is an American post-hardcore band from Findlay, Ohio.
 The band is currently signed to InVogue Records.
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.
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.
