In a similar fashion to Radiohead's latest album available for download at "you choose" prices, Saul Williams is doing a similar thing for his new album, which is produced with the heavy involvement of Trent Reznor of Nine Inch Nails fame. If you for some reason haven't ever heard Saul Williams' work, check it out - usually an amazing mix of Hip Hop/Rock/Poetry. The new album drops 1st Nov for downloads.

Usually I wouldn't plug something like this, but Saul Williams is an exceptional case.
