icepick…I love love love ambient music. and I mean DEEP, minimal, droney stuff.
when I first wanted to get into ambient music, I got recommendations like the Orb and Aphex Twin’s SAW II. both great stuff, but there was just something that I wanted to get into more. I wanted to go deeper.
enter Lull…the project from Mick Harris of Napalm Death and Scorn. his earlier stuff as Lull is more industrial ambient, but by “Cold Summer” (highly recommend that one) …it’s deep, heavy, droney material,as was all his output from that point on. I recommend his ENTIRE Lull catalog, it’s exactly what you’re looking for.
Oophoi is another top choice, in particular his Uputaut album, which is one hour+ long track, and the Spirals of Time 3 cd set, which is a live performance outdoors that spans all 3 discs.
I also recommend Final, the project from Justin Broadrick. I’m not TOO familiar with the most recent stuff as I’m not as big a fan of it, but I think you’ll like it as well. I will, however, recommend Solaris, his best album under the project. great guitar manipulations (you can’t tell they’re guitars) , feedbacks, hums, drones, etc.
Rapoon is another great project to check out, most specifically the Kirghiz Light 2 cd album, Fire at the Borderlands, and Darker by Light. Excellent ambient material, with at times a tribal style influence.
