John Oswald : Plexure
This is generaly regarded as sampling maestro Oswald's best work. Split-second samples of several hundreds of widely known hits (from Madonna to Milli Vanilli via Springsteen) but you have no time enough to recognize them. On-and-off available expensive Japan 1993 issue (double-CD price for 22 minutes of music - one can say 'it's worth it' but it will still be too much). A masterpiece of sorts, for sure. Don't miss also Oswald's other site, you can get there (among lots of great reading) a free download of his infamous 'banned' Plunderphonic CD that started the historic judicial battle and a worldwide copyright vs. sampling debate.
Note: Just found out that you can also download his great early Mystery Tapes & Kissing Jesus In The Dark from Ubuweb. Don't miss! Same also on the very interesting Detritus site archives, with some more similar stuff, incl. the truly great Negativland's U2 EP (thanks, Mr.Lucky for this!)
