What band asked the band who released an album called Last Splash to open for them in September?
In 1993, the Breeders released their second album, Last Splash. At this time, the group's lineup  consisted of sisters Kim and Kelley Deal on guitar and vocals, Josephine Wiggs on bass and vocals, and Jim Macpherson on drums. Last Splash was successful in various countries worldwide, and the group toured extensively and played at Lollapalooza 1994. In November 1994, Kelley Deal was arrested on drug-related charges, and in 1995, Wiggs left to pursue other musical projects. Macpherson continued playing with Kim Deal in her side-project group, the Amps, and then in the 1996 incarnation of the Breeders, but quit the band in 1997. The Breeders' lineups for their albums Title TK (2002) and Mountain Battles (2008) included the Deal sisters, Mando Lopez, and Jose Medeles. In 2013, Wiggs and Macpherson rejoined the Deals to tour the 20th anniversary of Last Splash—the LSXX Tour.On December 31, 2013, the Breeders performed their final concert on the 60-date tour in Austin, Texas. The group enjoyed the LSXX concerts, and decided they would like to record new music together. Throughout 2014, Wiggs traveled from her home in Brooklyn, New York to Dayton, Ohio, near where Macpherson and both Deals lived. The group began practicing new material in Kim Deal's basement, including compositions by her and one by Wiggs. By August, there were three new songs they could play well, two less so, and others they had not yet practiced. Reported titles were "Skinhead #2", "Simone", "All Nerve", and "Launched". The band Neutral Milk Hotel asked the Breeders to open for them at a Hollywood Bowl concert to be held on September 18. The latter decided to go on tour leading up to this show and to perform some new compositions in preparation for their eventual recording.
