Do it now you lazy toe-rag.
Make a thread of the same name as this, only in say 'General' for example (seeing as avant-garde and experimental music has influences across many genres) with a short explanation of the thread;
It's a fascinating subject.
Bands like the Velvet Underground, early Talking Heads, Frank Zappa, Eno, the Flaming Lips...the list is endless.
It opens a whole possibility for discussion about influential bands and the albums that have been released through the years that were ahead of their time and went on to be recognised as significant contributions towards developing modern music as it is now.
Do it and Ethan can delete this thread later.
Edit: It'll make a nice change from spray on condoms or who the latest boy/girl band is.
