You guys listed all the good ones, except the 4-disc Lost Legends of Surf Guitar, which is just amazing. Also, I really like "Experimental Japanese Music", this weird Japanese album with GRound Zero and a Takashii Miike interview in the middle of the whole thing. Also check out "Classical Chinese Music Played on Traditional Instruments". I did a comp a few years ago for xdiedenroutey called "Just Because your Music Wears Thin doesn't mean You're In Shape" which had new songs from Darth Vegas, Cock ESP, Point Line Plane, Violetta Beuaregarde, Warmth, Scissor Shock, Haunted Castle, Yellow Swans, and a ton more... here's a link to this Adam Cooley-curated comp tracklisting (which I have no copies of):
