What music is not derivative?


I was just reading up on some older posts about peoples opinions of some new bands. There are often times people complaining about music being so derivative and unoriginal. My question is what music released in the post Beatles era has been truly original?

I have a few ideas in mind, but will let y'all have the first shot at it.

radiohead's recent stuff (kid a, amnesiac) is pretty original. Also, Sigur Ros (Icelandic group, just kids really) is non-derivative. That's just as far as rock goes, which I think is what you're asking. But if you get into more experimental stuff... try Bernard Gunther or Kim Cascone - I guarantee you've never heard anything like their work.
Roxy Music and The Talking Heads were a much needed breath of fresh air in the late 1970's and 80's.
It could be argued that there is no such thing as music that is not derivative. I guess Derek Bailey, Edgar Varese, and most Anthony Braxton recordings might come close. Not sure you would want to listen to them much. Alot of great stuff is challenging, innovative and derivitave, (like Gentle Giant, Roxy Music or some Radiohead). Checking out Terje Rypdal, Uwe Koprinski, Squarepusher, Lucas Niggli(Zoom), X-Legged Sally, Sonny Sharrock (Sieze the Rainbow), Massacre (w/Fred Frith), Octavo, Steve Tibbets, Allan Holdsworth, Jean Derome, Eberhard Weber, David Torn or Egberto Gismonti might fire up some under used neurons.
I think it's all basically derivative, but that doesn't deter my enjoyment one bit. I think there are more excellent practitioners today than any time before, and I enjoy what they produce despite it being derivative.

As with many terms we use, derivative can by used as a descriptor or as an (implied) insult.

I'd be curious to look back in 100 or 200 years and see if history sees the Beatles and/or the 60's as being non-derivative.
