AACMP books/Chicago Mov't

i was curious if anybody knew of any books dealing with the AACMP, namely with chicago musicians along the likes of art ensemble. most especially something dealing strongly on the social commentary of the time and the musicians reaction. interviews, testimonials... etc. i am in the pre-stages of putting together a mock touring historical show for part one of my senior graphic design project and was hoping to use this area as a main focus. any websites, books (especially), real photos (willing to give credit where credit is due. NO EXCHANGE OF MONEY WILL TAKE PLACE IN THIS PROJECT, except what ever it may cost me to get stuff printed that cant be printed here at school). any help would be gladly appreciated! -darryl norsen
