when i started playing with samples in late 97, i was told by some older music fans that negativland is worth checking out. i spent quite a bit of time sorting through mp3s downloaded via ftp and didn't really find anything i could seriously relate to. it was very influential on me in an aesthetic sense though - it legitimized the idea i had of splicing samples together in weird ways.
(relevant tracks: inrisampled, eat my fuck, most of the connecting sections in the 1997/1998 material)
