I think the real dichotomy is more between modern composition and older works. I'm only interested in listening to Wagner or Mozart for so long, at some point I'd like to hear something that's fresh. But many of the modern composers seemed to me have lost sight of what sounds good, preferring to take some kind of conceptual approach that may be of interest to other composers but I find often isn't very interesting to listen to. After the likes of Xenakis, Philip Glass, Laurie Anderson and a few others, I found it to be mostly elitist insider music, and tuned out. And I'm a musician myself, but that kind of stuff just lost me. I now listen more to Chris Clark, Peter Scherer, and maybe John Zorn and some ethnic-fusion experimenters, Jazz and electronica artists and a few others who at least haven't lost sight of what sounds interesting. As far as I'm concerned, "purists" of any kind are tending towards boring. If you see your art as a museum piece be a purist and re-create that which has come before. But as I think Grace Slick once said, "Van Gogh never had to paint a painting twice."
