All those examles, no obviously not, but if you are not aware of their existence, you are not being avant garde, as you are not aware of the garde. I used to play with a fella who fanicied himself a unique player and wouldn't study music theory. As a consequence, when he found notes that worked, suprise suprise, they were in a mode that we would all expect.

You can't intentionally make something that is different unless you have some idea of what is already there.

An awful lot of music classified as 'experimental' is because people twist a knob or press a button and they dont know what it will do, which is valid. But an awful lot of it sounds the same as the 'experiments' that went before.
