Yeah production wise there's no arguement he's one of the legends, and his live PA's are pretty special too.
But DJing he does seem to be a little hit & miss. I've seen him absolutely tear it up at Atomic Jam a few times but then I've also seen him have a complete shocker, knocking the needle off the record with his elbow, trainwrecks etc. He's definately a talented DJ, just gets a bit sloppy from time to time.
