Since people are bringing up obvious things like Schimpfluch, COUM Transmissions was very obviously, heavily influenced by Viennese Actionism, though, since there's a chance that none of us would be here discussing what we're discussing without them, at least in some of the terminology we use, I guess that's even more obvious.
Valie Export was heavily influenced by the Actionists, and Viennese.
What about Karen Finley? I think I read somewhere that she was unaware of any of that stuff, but I can't remember.
