My friend Encyclopedia Brown compiled some links to some of DJ AM's mixes, along with links to DJs who knew him better. Check it over here.
LA's Glenjamn has over one hundred short videos that capture how great DJ AM was on the ones and two's. Video Archive. (Not everything will be AM, but its the easiest way to see most of the vids featuring him)
His other homie, Thee Mike B, will be digging through his archives to give you some killer mixes, so check out his blog from time to time.
Plus, the dude had a killer shoe game. Jaw-Dropping.
If you're looking for an article, then the Village Voice has you covered.
