Question: Did singer Julian Casablancas and band Hüsker Dü both play rock music?
Context: Julian Casablancas and the Voidz (stylised as Julian Casablancas+The Voidz and occasionally JCVZ), or simply The Voidz, are an American rock band formed by Julian Casablancas of The Strokes.  The band consists of Casablancas (lead vocals) as well as Jeramy "Beardo" Gritter (guitar), Amir Yaghmai (guitar), Jacob "Jake" Bercovici (bass guitar, synthesizers), Alex Carapetis (drums, percussion), Jeff Kite (keys) and Shawn Everett (production). The Strokes are an American indie rock band.  Formed in New York City in 1999, the group consists of singer Julian Casablancas, guitarists Nick Valensi and Albert Hammond Jr., bassist Nikolai Fraiture and drummer Fabrizio Moretti.  The Strokes discography consists of five studio albums, two extended plays (EP), twelve singles, one video album and fifteen music videos. 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. 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. "Reptilia" is a song by indie rock band The Strokes, and the second single from their second album "Room on Fire".  The single's B-side contains "Modern Girls & Old Fashion Men", where lead singer Julian Casablancas duets with Regina Spektor.  The official release date was delayed slightly after Casablancas objected to the song being credited as "The Strokes and Regina Spektor", claiming that it should read "Regina Spektor and The Strokes". Julian Fernando Casablancas (born August 23, 1978) is an American singer, producer, and songwriter.  He is the lead vocalist of the rock band The Strokes.  In addition to his work with The Strokes, Casablancas led a solo career during the band's hiatus, releasing the album "Phrazes for the Young" on November 3, 2009. 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. 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. 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.
