Rollercoaster Tour: 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).

My Bloody Valentine (band): My Bloody Valentine are an Anglo-Irish rock band formed in Dublin in 1983.  Since 1987, the band's lineup has consisted of founding members Kevin Shields (vocals, guitar) and Colm Ó Cíosóig (drums), with Bilinda Butcher (vocals, guitar) and Debbie Googe (bass).  The group are known for their integration of noise, melody, and unorthodox guitar and production techniques during the late 1980s and early 1990s, resulting in their pioneering a musical style known as shoegazing.

Ecstasy (My Bloody Valentine album): Ecstasy is the second mini album by the alternative rock band My Bloody Valentine, released on 23 November 1987 on Lazy Records.  Released in a limited edition of 3,000 copies, it was the band's final release for Lazy Records and second to feature vocalist and guitarist Bilinda Butcher, who was recruited in April 1987 following the departure of original My Bloody Valentine vocalist David Conway.  "Ecstasy" followed the noise pop and twee pop standards of My Bloody Valentine's earlier releases for the label, drawing influence from various artists including The Jesus and Mary Chain, Love and The Byrds, and the album distanced the band further from their earlier post-punk and gothic rock sound.

This Is Your Bloody Valentine: This is Your Bloody Valentine is the debut mini album by the alternative rock band My Bloody Valentine, released in January 1985 on Tycoon Records.  Recorded in West Berlin, Germany, it features the band's early gothic rock and post-punk sound, which contrasts the shoegazing sound with which My Bloody Valentine are associated.

List of songs recorded by My Bloody Valentine: My Bloody Valentine, an alternative rock band from Dublin, Ireland, have recorded songs for three studio albums and a number of extended plays, singles and compilation releases.  Formed in 1983 by Kevin Shields, Colm Ó Cíosóig and David Conway, the band had a series of unsuccessful releases throughout the mid-1980s on various independent record labels.  In 1987, after the addition of bassist Debbie Googe and vocalist-guitarist Bilinda Butcher, My Bloody Valentine released "Strawberry Wine", "Ecstasy", and the 1988 EP "You Made Me Realise", which were predecessors to the band's debut album "Isn't Anything" (1988).  Considered an independent success, the band released two further EPs before "Loveless" (1991), their second studio album; which is considered their "magnum opus" and which received unanimous critical acclaim since its release.  Both albums pioneered an alternative rock subgenre known as shoegazing, a term coined by "Sounds" journalists to describe certain bands' "motionless performing style, where they stood on stage and stared at the floor".  My Bloody Valentine disbanded in 1997 after failing to utilise a third album although Kevin Shields was rumoured to have sent 60 hours worth of material to Island Records, with whom the band signed after being dropped by Creation Records in 1991.  My Bloody Valentine reunited in 2007 and began completing their third album.  The album, "m b v", was self-released in 2013 and received "universal acclaim", according to Metacritic.

Kevin Shields: Kevin Patrick Shields (born 21 May 1963) is an American-born Irish musician, singer-songwriter, composer and producer, best known as the vocalist and guitarist of the alternative rock band My Bloody Valentine.  Shields performed in a number of small unsuccessful bands in Dublin, Ireland, as a teenager, before forming My Bloody Valentine with drummer Colm Ó Cíosóig in 1983.  Although initially experiencing limited success, the band would later become extremely influential on the evolution of alternative rock with their two original studio albums "Isn't Anything" (1988) and "Loveless" (1991), both of which pioneered a subgenre known as shoegazing.  Shields' texturised guitar sound and his experimentation with his guitars' tremolo systems resulted in the creation of the "glide guitar" technique, which became a recognisable aspect of My Bloody Valentine's sound, along with his meticulous production techniques.
