Damn, this isn't bad at all. 5 stars from AMG:

Before Aphex Twin, remixes were dancefloor fodder and singles filler, hired out and produced with an eye to crossover success in different markets with what was largely the same piece of music (apologies to masters of the form Tom Moulton, Shep Pettibone, and Arthur Baker). After Aphex Twin, dozens of electronic and experimental outfits considered entire remix albums de rigeur, a process certainly not influenced by the release of Madonna's You Can Dance or Paula Abdul's Shut Up & Dance. A remix, for the notorious recluse Richard D. James, was simply another way to release his music, and as the title of this remix collection indicates, earn some money off the backs of clueless record labels. (He often indicated a disdain for the artist he was working for matched by few excepting Steve Albini.) James created remixes using none of the source material given (for Nine Inch Nails, he admitted "I never heard the originals...I don't want to, either"), sent along work at the last minute with no connection to the artist involved (a random tape of gabba from his studio was handed over to an Atlantic rep for a Lemonheads remix), and even play the middle-man for the productions of his flatmate Global Goon. Nevermind the methods, it's clearly the results that count, and 26 Mixes for Cash comprises some of the most creative, breathtaking music produced by anyone in electronica -- from early successes, like the gloriously uncomplicated ambient pop of Seefeel's "Time to Find Me," to the latest offerings from an artist who should release more, an unlisted remix of 808 State's "Flow Coma" (titled, simply, "Remix by AFX").

I haven't heard this. I generally try to avoid remix albums in favor of original release material, partially out of habit and partially because I usually don't like them as much.

Most of the originals are pretty obscure. There's a Bowie remix and a NiN remix but the other 20 some acts I have never heard of.

You should get into some Gavin Bryars.
