EP's 1988–1991 ["sic"] is a compilation album by Anglo-Irish alternative rock band My Bloody Valentine, released on 4 May 2012 on Sony.
 It features three of the band's extended plays for Creation Records—"You Made Me Realise" (1988), "Glider" (1990) and "Tremolo" (1991)—plus one single ("Feed Me with Your Kiss"), and seven additional rare and unreleased songs.
 Compiled and remastered by the band's vocalist and guitarist Kevin Shields, "EP's 1988–1991" was released as a two-disc CD set alongside remastered versions of My Bloody Valentine's two original studio albums, "Isn't Anything" (1988) and "Loveless" (1991).
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.
Harry Warden is a character from the "My Bloody Valentine" films.
 He appears in George Mihalka's "My Bloody Valentine" and Patrick Lussier's "My Bloody Valentine 3D" as one of the main antagonists. Despite the "My Bloody Valentine" films not launching a franchise, Harry Warden has gained a cult status in the horror genre despite only appearing in two films.
 In the films, the killers including Warden, presume the identity of "The Miner".
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.
Sick Puppies EP is the fourth EP by Australia rock band Sick Puppies.
 The EP was sold at live events and is now only available on the secondhand market.
 The EP was released as an enhanced CD with bonus multimedia content featuring lyrics, a photo gallery, the YouTube Free Hugs video for "All the Same", and a live video trailer.
 All the tracks were re-released on the album Dressed Up As Life.
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.
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.
Sick Puppies is an Australian rock band, formed in 1997.
 Sick Puppies rose to prominence in 2006 when their song "All the Same" was uploaded along with a video to YouTube.
 The video supported the Free Hugs Campaign which was launched in Sydney, and has since received over 77 million views on the website.
 This success followed up with "Dressed Up as Life" in 2007, which entered the "Billboard" 200 at number 181.
 Their third studio album, released on 14 July 2009, is titled "Tri-Polar".
 The band's fourth studio album "Connect" was released on 16 July 2013.
 They released their fifth studio album "Fury" on 20 May 2016 with new vocalist Bryan Scott after Shimon Moore left the band on October 2014.
