Great dubstep record. Not really comparable with Aphex Twin , but at least it doesn't drone on for eternity :P.
And Boards of Canada of course ('Geogaddi', 'Music Has The Right to Children' or 'In A Beautiful Place Out in The Country'). There are some other pretty cool IDM records out on Warp too, like Black Dog Productions' 'Bytes'. And there are artists like J Dilla and Flying Lotus, who make more hiphop oriented electronic music but are still really cool.
