Question: Which band was formed in Seattle, Washington, Pop Will Eat Itself or Soundgarden?
Context: Because Seattle is Washington's largest city, the music of Seattle has long played a major role in the music of Washington, in genres of alternative rock that included grunge, and major bands like Nirvana and Alice In Chains Soundgarden as well as Pearl Jam.  Seattle remains home to several influential bands, labels, and venues. Pop Will Eat Itself (also known as PWEI or The Poppies) are an English alternative rock band formed in Stourbridge in 1986 with members from Birmingham, Coventry and the Black Country.  Initially known as a grebo act, their style changed to incorporate sample-driven indie and industrial rock.  Their highest charting single was the 1993 top ten hit, "Get The Girl!  Kill The Baddies!" .  After initially disbanding in 1996, and having a brief reformation in 2005, they issued their first release in more than five years in 2010. Chris Cornell was an American rock musician from Seattle, Washington.  He began his career in 1984 when he formed grunge band Soundgarden with guitarist Kim Thayil and bassist Hiro Yamamoto, originally playing drums in addition to vocals before Scott Sundquist took over the former the following year.  The group contributed three songs to the C/Z Records compilation "Deep Six" in 1986, before Sundquist was replaced by Matt Cameron.  After two extended plays (EPs), Soundgarden released its debut full-length album "Ultramega OK" in 1988, on which Cornell was credited for songwriting on all but one of the eleven original songs. " Louder Than Love" followed in 1989, on which Cornell was credited solely for writing seven of the album's twelve songs (and co-credited on four of the other five). Jack Endino (born 1964) is an American producer and musician based in Seattle, United States.  Long associated with Seattle label Sub Pop and the grunge movement, Endino worked on seminal albums from bands such as Mudhoney, Soundgarden, and Nirvana.  Endino was also the guitarist for the Seattle band Skin Yard which was active between 1985 and 1992.  Endino currently manages a studio in Seattle called Soundhouse Recording. Hater was an American rock band that formed in Seattle, Washington in 1993.  The band formed as a side project mostly under the direction of Soundgarden bassist Ben Shepherd.  Additional members included Soundgarden drummer Matt Cameron, guitarist John McBain (ex-Monster Magnet and, later, partner of Cameron and Shepherd in Wellwater Conspiracy), bassist John Waterman for the self-titled album, Devilhead vocalist Brian Wood, brother of Mother Love Bone vocalist Andrew Wood, and Alan Davis on bass for "The 2nd". Wellwater Conspiracy was an American rock band that formed in Seattle, Washington in 1993.  The band was created by members of the grunge-era side project Hater.  Wellwater Conspiracy featured Soundgarden drummer Matt Cameron and ex-Monster Magnet guitarist John McBain.  The band originally featured Soundgarden bassist Ben Shepherd, who left the band in 1998.  Various other artists have contributed to the band's albums, notably Queens of the Stone Age front man Josh Homme and Pearl Jam singer Eddie Vedder. Sub Pop is a record label founded in 1986 by Bruce Pavitt.  In 1988, Sub Pop Records LLC was formed by Pavitt and Jonathan Poneman in Seattle, Washington.  Sub Pop achieved fame in the late 1980s for first signing Nirvana, Soundgarden, Mudhoney and many other bands from the Seattle alternative rock scene.  They are often credited with taking the first steps toward popularizing grunge music, and have continued to achieve critical and commercial success in the new millennium, with bands such as Fleet Foxes, Foals, Beach House, The Postal Service, Flight of the Conchords, Sleater-Kinney, Blitzen Trapper, Father John Misty, Shabazz Palaces and The Shins on their roster.  In 1995 the owners of Sub Pop sold a 49% stake of the label to the Warner Music Group. Tad (often styled as TAD) was an American grunge band from Seattle, Washington, formed in 1988 by Tad Doyle.  Among the first of the many bands which came out of Seattle in the grunge era, Tad was notable for the fact that its music was inspired far more by 1970s metal (much like Alice in Chains and Soundgarden) than the punk which influenced many other grunge bands.  Although their commercial success was limited, their music is still highly regarded amongst grunge fans. Matthew David Cameron (born November 28, 1962) is an American musician who serves as the drummer for the American rock bands Pearl Jam and Soundgarden.  After getting his start with the Seattle, Washington-based bands Bam Bam and Skin Yard, he first gained fame as the drummer for Soundgarden, which he joined in 1986 and remained in until the band's break-up in 1997.  In 1998, Cameron was invited to play on Pearl Jam's U.S. Yield Tour.  He soon became a permanent member and has remained in the band ever since.  In 2010, Soundgarden reunited for a tour and released a new album, "King Animal," on November 13, 2012. Soundgarden is an American rock band formed in Seattle, Washington, in 1984 by singer and rhythm guitarist Chris Cornell, lead guitarist Kim Thayil, and bassist Hiro Yamamoto.  Matt Cameron became the band's full-time drummer in 1986, while bassist Ben Shepherd became a permanent replacement for Yamamoto in 1990.  The band dissolved in 1997 and reformed in 2010.  Cornell remained in Soundgarden until his death in May 2017, putting the band's future in doubt and leaving Thayil as the only remaining original member of the band.
