Another vinyl record retrieved from my parents, this is officially a single (and a 12" single at that), but it is basically the length of a short album and I have always approached it as such, for all that it is one track over the two sides of vinyl. This is also is famously the longest record ever to make the top twenty or something, as it is exactly what was then (in 1992) the maximum length permitted for a single. The whole piece is a dub influenced slice of ambient house (remember that?), with an insistent bassline, an unintrusive drumbeat that you could dance to if you were completely mashed on drøgs but would ignore otherwise, and a general aquatic feel. I gather that the Orb promoted this on Top of the Pops by playing a form of chess on a spherical board. Anyway, this is still a classic and I am very glad I own it.
