My favoritest ambient album ever is a 1992 album of "remixes and re-recordings" of Coil's 1984 debut single "How to Destroy Angels" (subtitle: "Ritual music for the accumulation of male sexual energy"). "Remixes" seems to mean "we recorded some new music with the same instruments". This one's the standout (other than the title track), a growling noise symphony that gives me stark images of looming forms gyrating in darkness.
