AMP: Artists' Meeting Place and Resource Collective

I am preparing a book on Artists and Politics in the US, I especially focus on artists' reactions to the war in Iraq. My work is based on interviews with committed artists.
I am University professor in Paris and I am currently in Los Angeles, affiliated with UCLA. I am in town until mid-December.
I am looking for artists who are politically active and/or are political in their artwork.
Please feel free to contact me and let me know if you have any question! Thank you.
