What is some Popular/rock music that you listen to that incorporates elements of of the avant garde?
Specifically these elements might include music concrete (found sounds and sound effects), aleatoric (chance) elements, use of noise, non-melodic synth elements, extended techniques, etc.
I am writing a paper for my Master's concerning this and any suggestions of where to look are appreciated.
Obvious examples are Revolution 9 (Beatles), much early Mother's of Invention, even Chicago (Free Form Guitar off of CTA). What are some others? I am primaily interested in the rock era between 1960 and 1980 but precursors and followers are appreciated as well. Help me out. I look forward to your input.
However, I am not really looking for aesthetic judgement. If you think avant garde concepts and elements are crap (and many do), then start a thread entitled "Avant Garde = Hammered Dog Sh*t" and I am sure we can all participate in that discussion

Thanks!
