Question: What musical strengths do Naser Mestarihi and Ben Weasel share?

Context paragraphs:
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.

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.

These Ones Are Bitter: These Ones Are Bitter is the second solo-album by Screeching Weasel front man Ben Weasel.

Naser Mestarihi: Naser Mestarihi (Arabic: ناصر شاهر صالح المستريحي; born 14 October 1987) is a Qatari born Jordanian-Pakistani singer-songwriter and multi-instrumentalist (guitars, bass & vocals) who is based out of Doha, Qatar and Dubai, United Arab Emirates.  Naser is the first rock musician to ever officially release a rock album out of Qatar, the "Naser Mestarihi EP".  He released his second album "1987" on 17 June 2013.

Panic Button Records: Panic Button Records was a record label which was formed in Chicago, Illinois in 1997.  It was co-owned by Ben Weasel and John Jughead, both members of Screeching Weasel.  In 1998 the label was purchased by Lookout!  Records when Screeching Weasel re-signed to Lookout! .

1987 (Naser Mestarihi album): 1987 is the full-length debut of Doha/Dubai based hard rock singer-songwriter Naser Mestarihi.  The album was released on June 17, 2013.

Naser Mestarihi EP: Naser Mestarihi EP is the eponymous debut EP of Doha based hard rock guitarist Naser Mestarihi.  The release of the album marked the first official release of a rock album out of Qatar.  All the lyrics and music on the album were written by Mestarihi, who also plays all the instruments with the exception of the drums.

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.

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.

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.
