Question: Which of the following is a rock band led by singer and guitarist Bob Mould: Bracket or Sugar?
Context: Red Heaven is a 1992 album by the American alternative rock band Throwing Muses, released on Sire/Warner Bros.  Records.  Recorded at The Power Station and Fort Apache Studios following the departure of Tanya Donelly and Fred Abong, "Red Heaven" was recorded by Kristin Hersh and drummer David Narcizo with help from former bassist Leslie Langston.  Former Hüsker Dü vocalist/guitarist Bob Mould took time off from his new band Sugar to record vocals for "Dio".  Initial copies of the album came with the otherwise unavailable Kristin Hersh solo acoustic album "Live at Maxwell's Hoboken". 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." 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. 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. Sugar was an American alternative rock band of the early 1990s.  Formed in 1992, they were led by the singer and guitarist Bob Mould (ex-Hüsker Dü), alongside bassist David Barbe (ex-Mercyland) and drummer Malcolm Travis (ex-Human Sexual Response). 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. 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. Bracket is an American rock band from Forestville, California formed in 1992.  The lineup consists of lead vocalist and guitarist Marty Gregori, bassist and backing vocalist Zack Charlos, drummer Ray Castro, and guitarist and backing vocalist Angelo Celli, who replaced Larry Tinney in 1998.  Bracket has issued numerous albums, EPs and singles since its inception, including many releases for Caroline Records and Fat Wreck Chords.  Their sound could most easily be described as power pop influenced punk rock with a continued focus on vocal harmonies.
