Question: Which musician is a member of Me First: Spike Slawson or Grant Hart?

Context paragraphs:
Spike Slawson: Spike Slawson is an American punk rock musician, a member of Me First and the Gimme Gimmes, Swingin' Utters, Filthy Thievin' Bastards, Re-Volts, and Uke-Hunt.

Oeuvrevue: The album is a collection of B-sides, live recordings, radio sessions and outtakes recorded by Grant Hart as a solo artist and as part of Nova Mob.  Originally released in a limited edition of 1000 copies to coincide with Hart’s fall 2010 European tour.

Uke-Hunt: Uke-Hunt is a ukulele-based cover band fronted by Spike Slawson from Me First and the Gimme Gimmes.  Although both this and the Gimmes are cover bands, they have very different approaches.  While the Gimmes generally pick non-rock songs and rock them out and speed them up to turn them into punk music, while in this band, the songs picked are generally upbeat songs that are then slowed down and mellowed out.

The Argument (Grant Hart album): The Argument is the fourth and final solo studio album from Grant Hart, formerly of the band Hüsker Dü.  The album was released in 2013, four years before Hart's death.  It is a concept album based on John Milton's "Paradise Lost", and inspired by Hart's friendship with renowned beat author William S. Burroughs.  The album features guitar, keyboards, mallet instruments, and found sounds.  It was released to universal critical acclaim.

Warehouse: Songs and Stories: 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: 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.

The Dwarves Must Die: The Dwarves Must Die is the 2004 release by the American punk band Dwarves.  It is the band's first release on the "Sympathy for the Record Industry" label.  There are several cameos, including Dexter Holland from The Offspring, Nash Kato from Urge Overkill, desert rock icon Nick Oliveri, Josh Freese from The Vandals, Spike Slawson from Me First and the Gimme Gimmes, gangster rapper San Quinn, DJ Marz, and even the original Space Ghost himself, Gary Owens.  The rather freeform departure from the standard thrash/punk/noise sound is obvious in this release, slightly more so than in previous Dwarves productions, perhaps because they have been producing music for almost 20 years; however the original sound of the Dwarves shows clearly in several tracks.

Filthy Thieving Bastards: The Filthy Thieving Bastards is an American folk/punk rock group formed in 2000 in San Francisco, California.  The band was originally a side project put together by Johnny Bonnel and Darius Koski of the Swingin' Utters.  Spike Slawson (also from Swingin' Utters) later joined the band, along with recording engineer Randy Burk.  Greg Lisher from Camper Van Beethoven guested on guitar for several songs on their second release.  Their music is influenced by folk rock, Celtic rock, country music, 60's pop, and punk rock, with an acknowledged and oft-noted debt to the music of The Pogues.

Hüsker Dü: 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.

Grant Hart: Grant Vernon Hart (March 18, 1961 – September 13, 2017) was an American musician, best known as the drummer and co-songwriter for the alternative rock and hardcore punk band Hüsker Dü.  After the band's breakup in 1988, he formed the alternative rock trio Nova Mob, where he moved to vocals and guitar.  His solo career became his main focus after the dissolution of Nova Mob in 1997.
