Not surprisingly, you're quite correct, Geoff. Now it's your turn.

okay,

here is my first picture.

I'm going to say Han Bennink...

...I'm also going to say that is one hillarious picture. :tongue:

Han Bennink is correct.

I have a wall-paper sized version of this image.

It was my wallpaper on my computer for a long time.

(edit: your turn)

All right, who is this avant-gardist:

That is Harry Partch

You got it...as usual.

Your turn...

I am undefeatable.

My knowledge of music is more immense than anyone else on this forum

Mwahahahaha

Well enough of that,

here is your next one

I'm thinking it's Lee Perry...but he's not really what I'd consider avant-garde...so I'm probably wrong...

yeah it is lee "scratch" perry.

He isn't too much of an avant-garde musician, but I just thought it was a funny picture.

He is pretty much an experimentalist in his field of work though.

His latest album features some pretty cool vocal experiments.
