I know the person who does the mashups I like so much, so this thread is for them and discussing them if you are willing to listen.
Excellent Examples of their "repertoire" (well actually most of their stuff):
Pretty:Post-Romantic:Dark:
Boulez:Morton Feldman:Mashed up Concerti:
I hope at least some of you peak at this. I find it fascinating to see old material in new contexts.
My personal recommendations are:
Prelude to a Buddhist Daphnis
Sibelius' Dream Symphony Poem
Ligeti's Final Requiem
Messiaen's and Boulez's - Pli selon La Transfiguration de Notre Seigneur
Feldman's Concertante Puzzles
Unsuk Chin's Imaginary Quadruple Concerto-Fantasy
