The piece was inspired by drone music, with a text from La Monte Young in the liner notes.

It was recorded in the foyer of a cinema as an audience waited for a screening of the film Wings of Desire; crowd noise and public-address announcements are audible.

A brief melodic fragment from the improvisation was re-used as the basis for the song "Honey" from the group's 1989 album Playing With Fire.

"[3] The other track on the original vinyl release "Ecstasy in Slow Motion" is a studio performance from 1987 which only features Pete Kember.

"Spacemen Jam", which appears on subsequent reissues, is Peter Kember and an unknown second guitarist, possibly Jason Pierce.
