Question: Which group was founded earlier, Uncle Tupelo or Soundgarden?
Context: Uncle Tupelo was an alternative country music group from Belleville, Illinois, active between 1987 and 1994.  Jay Farrar, Jeff Tweedy, and Mike Heidorn formed the band after the lead singer of their previous band, The Primitives, left to attend college.  The trio recorded three albums for Rockville Records, before signing with Sire Records and expanding to a five-piece.  Shortly after the release of the band's major label debut album "Anodyne", Farrar announced his decision to leave the band due to a soured relationship with his co-songwriter Tweedy.  Uncle Tupelo split on May 1, 1994, after completing a farewell tour.  Following the breakup, Farrar formed Son Volt with Heidorn, while the remaining members continued as Wilco. Anodyne is the fourth and final studio album by alternative country band Uncle Tupelo, released on October 5, 1993.  The recording of the album was preceded by the departure of the original drummer Mike Heidorn and the addition of three new band members: bassist John Stirratt, drummer Ken Coomer, and multi-instrumentalist Max Johnston.  The band signed with Sire Records shortly before recording the album; "Anodyne" was Uncle Tupelo's only major label release until "" in 2002. A.M. is the debut studio album by the American alternative rock band Wilco, released on March 28, 1995, by Sire Records and Reprise Records.  The album was released only months after the breakup of Uncle Tupelo, an alternative country band that was the predecessor of Wilco.  Prior to its release, there was debate about whether the album would be better than the debut album of Son Volt, the new band of former Uncle Tupelo lead singer Jay Farrar. Jeffrey Scot Tweedy (born August 25, 1967) is an American songwriter, musician, and record producer best known as the singer and guitarist of the band Wilco.  Tweedy, originally from Belleville, Illinois, started his music career in high school in his band The Plebes with Jay Farrar, which subsequently after several years formed into the alternative country band Uncle Tupelo.  After Uncle Tupelo's fourth studio album, the band broke up in 1994 due to conflict between Tweedy and Farrar, prompting Tweedy to form Wilco, with Farrar forming the band Son Volt.  Wilco's first album "A.M.", released in 1995, received mixed reviews from critics, though Wilco later found critical and commercial success on their later albums, most notably with "Yankee Hotel Foxtrot" and "A Ghost Is Born", the latter of which received a Grammy for Best Alternative Album in 2005.  Across Tweedy's career he has released fifteen studio albums, including four with Uncle Tupelo, ten with Wilco, and one with his son Spencer, along with numerous collaborations with other musicians, most notably "Mermaid Avenue" with Billy Bragg. Grandpa’s Ghost is an experimental American band from Pocahontas, Illinois.  The group was founded by Ben Hanna and Bill Emerson in 1995 on the outskirts of St. Louis, Missouri, in Pocahontas & Pierron, Illinois and was initially associated with the second wave of alt-country music from the region that included Uncle Tupelo, The Bottle Rockets, Son Volt, and Wilco.  The current lineup features Hanna, Emerson, and Jack Petracek. The 1883 Philadelphia Quakers season was the first in the franchise's existence.  The team was founded earlier in the year as a replacement for the Worcester franchise.  It was the first year Philadelphia was represented in the National League since the original Athletics were disbanded in 1876.  The American Association's Philadelphia Athletics had been founded a year earlier. No Depression is the first studio album by alternative country band Uncle Tupelo, released in June 1990.  After its formation in the late 1980s, Uncle Tupelo recorded the "Not Forever, Just for Now" demo tape, which received a positive review by the "College Media Journal" in 1989.  The review led to the band's signing with what would become Rockville Records later that year.  The album was recorded with producers Sean Slade and Paul Q. Kolderie at Fort Apache Studios, on a budget of US$3,500. Wilco: Learning How to Die (2004, ISBN  ) is a book by "Chicago Tribune" rock critic Greg Kot.  The book was written with the cooperation of Wilco band members past and present.  It covers the time period from when Wilco singer Jeff Tweedy was born, through the formation and breakup of Uncle Tupelo, and the career of Wilco through their 2004 album "A Ghost Is Born".  It is primarily written as an oral history, featuring interviews with Tweedy, John Stirratt, and other Wilco members, as well as manager Tony Margherita and Uncle Tupelo drummer Mike Heidorn.  The book's title comes from a lyric of Wilco's "War on War", which appears on their 2002 album "Yankee Hotel Foxtrot".  It was published on June 15, 2004 by Broadway Books.  The book received positive reviews from outlets such as "The New York Times". 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. Mike Heidorn, born 1967 in Belleville, Illinois, is the former drummer and founding member of alternative country bands Uncle Tupelo and Son Volt.  Heidorn also played with the Uncle Tupelo precursors the Primitives (or Primatives ) and the one-off band Coffee Creek with Jay Farrar and Jeff Tweedy of Uncle Tupelo and Brian Henneman of The Bottle Rockets.  Heidorn married and left Uncle Tupelo after the recording of their third album, March 16–20, 1992.  After the breakup of Uncle Tupelo Heidorn was reactivated by Farrar and joined the first version of Son Volt, but was not involved in the reformation of the band in 2005 and is no longer active as a professional musician.
