This is the title track to the 1991 release ‘Analogue Bubblebath‘ by AFX, one of Aphex Twin‘s many pseudonyms. It is his first release under the AFX moniker. pRichard D. Jams (aka AFX) originally recorded the track in 1987, at the age of 16.
An aptly named classic, it really is a bubble bath for your ear canal. The EP continues with the much harsher and more discordant ‘Isopropophlex’ followed by an epic and chaotic ‘Entrance to Exit’, and it closes with some classic Aphex acid in ‘AFX 2’.
Not my favorite AFX release, but one of my favorite AFX tracks of all time, a true hallmark of ambient techno.
Sorry for the crap sound quality. Go buy the EP!
