I really love artist that push and sometime break boundaries, leading to a new style or vocabulary, or even redefining what constitutes art or not. Marcel Duchamp, John Cage, and maybe Andy Kaufmann would be examples of the latter. Other innovators, who may not cause us to re-think art, but I still I like a lot are Frank Zappa, Miles Davis, Jimi Hendrix, James Brown, to name a few. This is a thread to discuss innovations of specific artists as well as innovations in art more generally. I want to start by talking about two different innovations in music that I’m interested in.
