I finally got to see Gangs Of New York after finding a cheap DVD recently. I was astonished to hear the soundtrack - there were a few cuts from one of my favorite CD's called Altamont, which was made from field recordings of superb black old time string bands in the forties, including Lusk Gribble and Yorke. Probably not in the right place (they were Southerners) but great anyway.
