Feel free to call me all sorts of horrible things for posting this. I don't have any interest in electronic music or hiphop, really (give me folk or country any day), but I do love a challenge. Anyone got any real experience playing with music based on samples or DJs mixing vinyl? I figure you REALLY would have to rely on your ears - I'm guessing DJs generally don't give you charts, can't tell you what chord progressions, keys etc. they're working with... A DJ who's able to listen to you and adjust what he's doing accordingly could be a lot of fun to play with and completely different than playing with live instrumentalists, too.
