Context: The Rollercoaster Tour was a 1992 co-headlining concert tour by the English Britpop band Blur, the American indie rock band Dinosaur Jr., the Irish alternative rock band My Bloody Valentine and the Scottish noise pop band the Jesus and Mary Chain.  A one-leg 11-date tour of the United Kingdom, the tour was in support of all four bands' current releases: Blur's debut album "Leisure" (1991), Dinosaur Jr.' s fourth album "Green Mind" (1991), My Bloody Valentine's second album "Loveless" (1991) and The Jesus and Mary Chain's fourth album "Honey's Dead" (1992). Without a Sound is the sixth studio album by alternative rock band Dinosaur Jr., released on August 23, 1994.  It is the first Dinosaur Jr. album not to feature Murph on drums, who is replaced by vocalist and guitarist J Mascis.  It is also their most commercially successful album, peaking at number 44 on the Billboard Top 200. " Feel the Pain" and "I Don't Think So" were released as singles, with "Feel the Pain" reaching number 4 on the Billboard Modern Rock Tracks chart, becoming one of their biggest hits.  Mascis later admitted that his father's death affected his writing and performance on this album, and he took three years to deliver the next Dinosaur Jr.  LP, 1997's "Hand It Over". Emmett Jefferson Murphy III (born December 21, 1964), professionally credited as both Patrick Murphy and Murph, is best known for being the drummer for the alternative rock band Dinosaur Jr. He was a member of the group from its founding in 1984 through 1993, and since the original lineup reformed in 2005.

Inherit is the third album by the American band Free Kitten, released on May 20, 2008.  It was their first album in over ten years, the last being 1997's "Sentimental Education".  Dinosaur Jr.'s J Mascis appears on two songs on this album, "Surf's Up", and "Bananas". "Feel the Pain" is a single by alternative rock band Dinosaur Jr. from their 1994 album "Without a Sound".  When interviewed by Billboard magazine the producer and mixer for Dinosaur Jr., Agnello, explained that he was after a "dry" sound to the song, "…so dry it jumps out at you."  Despite bashing "Without a Sound" as a whole, "Feel the Pain" was one of the two songs (the other being "I Don't Think So") that music critic Stephen Thomas Erlewine felt was a success.  The music video was directed by Spike Jonze. Nature Nurture is the second studio album by British alternative rock band Dinosaur Pile-Up.  The album was released on 17 June 2013 and 25 February 2014 in the United Kingdom and the United States, respectively.  The album failed to chart in either of those countries.  However, the band's newfound popularity in Japan, along with the release of the "Peninsula EP" by A-Sketch months prior to the album's 22 October 2014 release, saw it chart at #168 in the country.  The single "Arizona Waiting" reached #68 on the Billboard Japan Radio Songs chart shortly after the album's release.  A-Sketch also released two "Japan Limited" music videos, both consisting of live performance footage, for "Peninsula" and "Arizona Waiting."
