I keep getting drawn back into the seemingly bottomless world of remixes by The Orb. This one's from a 12" released in 1992 and is the third and lengthiest of the pack, a long dub groove bringing together the best parts of Mixes 1 and 2 while extending them outwards.
Blue Pearl were best known for their 1990 hit Naked In The Rain, chart rave which I've got a soft spot for. Produced by Youth, hence the remix connection. 808 State's Graham Massey was involved in producing and remixing too.
