It could be said that Satie pioneered some of the first examples of
'Avant garde' music. He was more involved with the Surrealists though,
wasn't he?
He did ballets like parade just to bother the audience.
Picasso did backgrounds and costumes...etc.
The audiences of his openings would boo and hiss and throw things.
In general, a great artistic endeavor.
Heh.
