Question: Which is a punk rock musician, John Mayer or Ben Weasel?

Context paragraphs:
Ben Weasel: Ben Weasel (born Benjamin Foster) is a punk rock musician, best known as the lead singer and guitarist of the band Screeching Weasel.  He is also the co-host of "Weasel Radio", a weekly radio show formerly on ESPN 1070, which has been relaunched as a podcast.

Phase Three: Phase 3 is the third studio album by the American punk rock band The Riverdales.  It was released in 2003 through 1-4-5 Records.  It was the first new Riverdales album in five years, and the first Riverdales album to feature drummer Dan Lumley.  It was re-released on October 7, 2008 by Asian Man Records, who had also reissued the band's first album "Riverdales" in 2006.  The album was completely re-mixed and re-mastered, including five previously unreleased songs and new artwork.  Four of the bonus tracks were totally new and one was a new arrangement and recording of "Mental Retard" (from the "Storm the Streets" album).  Although the reissue was advertised as having re-recorded vocals, Ben Weasel has stated that this is not correct.  The lyrics to the song "Last Stop Tokyo" are printed on the back of the CD insert and was the first time that the Riverdales released any lyrics to the public.  Although written by Ben Foster, the song "Wait It Out" was first recorded by The Lillingtons on their 2001 album "The Backchannel Broadcast".  Since the relationship between Asian Man and all Ben Weasel related music is now severed, the album may be re-issued yet again sometime in the future.

First World Manifesto: First World Manifesto is the twelfth full-length studio album by the American punk rock band Screeching Weasel.  It was released on March 15, 2011, on Fat Wreck Chords and is the band's first album in eleven years.  It was produced by Mike Kennerty of The All-American Rejects, who has worked with Ben Weasel before on "These Ones Are Bitter" in 2007.

John Mayer: John Clayton Mayer ( ; born October 16, 1977) is an American singer-songwriter, guitarist, and producer.  He was born in Bridgeport, Connecticut, and raised in nearby Fairfield.  He attended Berklee College of Music in Boston, but disenrolled and moved to Atlanta in 1997 with Clay Cook.  Together, they formed a short-lived two-man band called Lo-Fi Masters.  After their split, Mayer continued to play local clubs—refining his skills and gaining a following.  After his appearance at the 2001 South by Southwest Festival, he was signed to Aware Records, and then Columbia Records, which released his first EP, "Inside Wants Out".  His following two full-length albums—"Room for Squares" (2001) and "Heavier Things" (2003)—did well commercially, achieving multi-platinum status.  In 2003, he won the Grammy Award for Best Male Pop Vocal Performance for the single "Your Body Is a Wonderland".

My Brain Hurts: My Brain Hurts is the third studio album by the Chicago-based punk rock band Screeching Weasel.  The album was originally released on CD, vinyl and cassette in September 1991 through Lookout Records.  It was the group's first album on Lookout as well as the only release with bassist Dave Naked and the first with drummer Dan Panic, the latter of which would go on to appear on several of the band's albums.  The album marked a very distinct stylistic shift for the group, fully moving toward a Ramones-inspired sound and completely abandoning their previous hardcore punk influences as a condition made by vocalist Ben Weasel when reforming the band after a brief break-up.

Major Label Debut: Major Label Debut is the tenth EP by Chicago punk rock band Screeching Weasel.  Despite the name, the E.P. was the first release on Panic Button Records, an independent record label owned by band members Ben Weasel and John Jughead.

Screeching Weasel: Screeching Weasel is an American punk rock band originally from the Chicago suburb of Prospect Heights, Illinois.  The band was formed in 1986 by Ben Weasel and John Jughead.

Riverdales: The Riverdales were an American punk rock band from Chicago, Illinois made up of Screeching Weasel members.  Bassist Dan Vapid (Dan Schafer) and guitarist Ben Weasel (Ben Foster) are heavily influenced by the Ramones' sound and both serve as front-men, sharing lead vocals for the band.  The Riverdales' original run lasted from 1994-1997.  They reformed in 2003 to record their third studio album, and then parted ways until they once again reformed in 2008 and released a fourth studio album in July, 2009.  The band's fifth studio album, "Tarantula", was released digitally on June 8, 2010 and on CD and vinyl on June 22, 2010.  The band broke up in March 2011 after a fight that broke out during a Screeching Weasel performance.

Storm the Streets: Storm the Streets is the second studio album by the American punk rock band the Riverdales.  After a dispute with Lookout!  Records, the band signed to Honest Don's Records for this release.  It is the only Riverdales album still available from its original label.  In the liner notes to Screeching Weasel's "Thank You Very Little" (2000), Ben Weasel refers to "Storm the Streets" as a "gem" but admits that the record sold far less than its predecessor, "Riverdales" (1995).  The band broke up with the album's release.  "I Accuse My Parents" most likely takes its title from a movie of the same name which was featured on "Mystery Science Theater 3000", a television show mentioned in the song "I Think About You During the Commercials" from the Riverdales' debut album.

Emo (album): Emo is the tenth studio album by the American punk rock band Screeching Weasel.  It was released on May 18, 1999 through Ben Weasel's and John Jughead's label Panic Button Records.  It was their first full length record released through Panic Button Records.  The album was recorded in Chicago during the blizzard of 1999.  Although the title of the album is a tongue-in-cheek stab at the emo scene that was about to break mainstream at the time, the songwriting on the album is extremely emotional and confessional.  Lyricist Ben Weasel had used this style of songwriting many times on previous albums, but this marked a noticeable change in tone.
