also, sadly, because there was never really any more to make it a "sound". He's a good example, because oddly he kinda sits outside culture a bit, pops up, does his thing and then was gone far too soon.
If you compare it to something else that was fairly original (at the time, and in the mainstream), like I dunno, Kid A, or Screamadellica - then the culture and the music form around each other - it's not as much that the music sounds dated, it's that the culture of the time picked up resonances of the music and vice versa.
