Aphex Twin - Digeridoo

Track 4 is actually Phloam, but is mislabeled as Isoprophlex.
Isoprophlex is only on the Belgium 12" pressing (as an extended version compared to the original version of the song from the first Aphex Twin release Analogue Bubblebath). The UK vinyl issue also has Phloam instead of Isoprophlex. UK CD and 12" are the same. Belgium 12" does not have the track Analogue Bubblebath 1 (which is a slightly shorter edit compared to the original from the Analaogue Bubblebath ep).

This ep is reprinted on Classics along with the Xylem Tube ep. That reprinting includes both the extended version of the track Isoprophlex and the slightly edited version of the track Analogue Bubblebath.
