Question: Who has been a member of more bands, Glen Benton or Spike Slawson?
Context: Glen Benton (born June 18, 1967) is an American death metal musician.  He is best known as the lead vocalist and bassist for the death metal band Deicide and was also a part of the band Vital Remains, where he has performed in recording sessions as well as live with them on a few occasions.  He is currently collaborating with Egyptian Artist Nader Sadek on his next record " The Malefic: Chapter II".  He is known for very low guttural growls as well as very high shrieks. 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. 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. 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. Till Death Do Us Part is the ninth studio album by American death metal band Deicide, released on April 28, 2008.  This is the band's longest album having 42:15 minutes long and presents some Doom Metal influences.  Initial copies of the album included a sew-on patch with an image of vocalist Glen Benton and the phrase "Glen Benton for President".  The album was also released on several colours of vinyl in limited numbers.  The artwork of the album cover is a segment of the painting "Woman and Death" (1518-1520) by Hans Baldung. 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 Stench of Redemption is the eighth studio album by American death metal band Deicide.  It is the first album by the band to feature Jack Owen (formerly of Cannibal Corpse) and Ralph Santolla (formerly of Iced Earth) on guitars.  Some editions of the album include a cover of "Black Night" by Deep Purple, with rewritten lyrics by Glen Benton. Dechristianize is the fifth album by American death metal band Vital Remains.  It was released on August 22, 2003.  The lyrics deal with the Dechristianization of France during the French Revolution.  The intro - "Let the Killing Begin" - features a section of Carl Orff's "O Fortuna" and voices from the movie "The Greatest Story Ever Told".  This album was the first to feature Deicide vocalist Glen Benton, and is generally considered to be the band's breakthrough album. Icons of Evil is the sixth album by Vital Remains.  It was released in April 2007.  The sample in "Where is Your God Now" is taken from the Mel Gibson film "The Passion of the Christ" and from William Peter Blatty's "The Exorcist".  "Icons of Evil" is the last album to feature vocalist Glen Benton and guitarist Dave Suzuki. Eaten Back to Life is the debut album by American death metal band Cannibal Corpse.  It was released on August 17, 1990, through Metal Blade Records.  The album was banned in Germany—censored versions of the album were not available, but the ban was revoked in June 2006 —and other countries because of the violent cover and the extreme nature of the lyrics.  Glen Benton of Deicide and Francis H. Howard of Opprobrium (then known as Incubus) perform back-up vocals on "Mangled" and "A Skull Full of Maggots".
