It was released as a limited edition free single with the first 5,000 LP copies of the band's debut studio album Isn't Anything, released on 21 November 1988 on Creation Records.

[4] "Instrumental No 2" features an uncredited sample of "Security of the First World", a song by Public Enemy from their 1988 studio album It Takes a Nation of Millions to Hold Us Back.

"Instrumental No 1" and "Instrumental No 2" were composed by vocalist and guitarist Kevin Shields,[6] with the latter being referred to as "a real acid-house track" by Shields and "an uncanny prophecy of [1990s] drum and bass jungle" by music critic Simon Reynolds.

[7] Shields later incorporated elements of dance music on My Bloody Valentine's 1990 single "Soon", which was released on both Glider (1990) and Loveless (1991),[8] and elements of jungle music on their third studio album m b v (2013).
