Cocteaus.. great band... seen them a few times (in fact they were one of the first bands I saw, when they were touring Treasure - at the old Saddlers Wells theatre)....
good intros - if the Pink Opaque is the comp I think it is, it's the 2 x 12" Tiny Dynamine & Echoes in a Shallow Bay combined - and well worth a listen. If not, both these 12"s are great...
Garlands through to Blue Bell Knoll are all fantastic
albums.
Garlands and Head Over Heels have some pretty standard Goth influences but the overall mood, sound & structure of both the albums make them well worth checking out.
Treasure, Victorialand and Head Over Heels are all well-worth spending time with, and there's a bit more breathing space on them than there is the first two albums.
The Pearly Dewdrops Drops and Aikea-Guniea eps are also must-haves.... personally I lost interest a little by the time of Heaven Or Las Vegas due to a slight case of overbombing I guess, but by all accounts the later work stands up pretty well too...
also worth checking out for an idea of the context of 4AD records at the time are the first This Mortal Coil album It'll End in Tears and the 12" Song to The Siren - and for the classy cover of the Tim Buckley with Liz Fraser vocals...
