your guess sounds pretty much correct - FACT says:
"The music is an atmospheric blend of low frequencies and chirruping samples evocative of (and perhaps sourced from?) this area of London. Fans of The Caretaker would do well to check it out.
Opening track 'Bunhill' loops a line from Blake's poem 'The Tyger' ("When the stars threw down their spears / And watered heaven with their tears") and sets it to a sparse dub rhythm reminiscent of Shackleton's Skull Disco and Mordant Music tracks. Elsewhere, ghost traces of junglist breaks and spoken incitations to rave are mingled with doomy, pseudo-occult ambience, as if those "clandestine events" from throughout history are happening all at once."
sounds well sweet to me, but i admit i'm wary of buying music without hearing it first
