your rant reminded me of something my friend Brandon said. DJing is a re-interpretation of pre-recorded music. When rave djs started playing, hip hop djs didn't think they were djs. When CDJs (and final scratch) got big, some vinyl djs didn't consider it DJing. Its a great argument.
but i also look at what all those forms of performance have in common = beatmatching. and what doesn't Remixing (in the studio sense) require? Realtime Beatmatching. And since so many traditional vinyl DJs and their followed generations of CDJ/FS/Traktor DJs hold the action of beatmatching so dear. I really think its only fair to call with Surgeon, Ruskin, Sasha, etc. do "Live Remixing". And i doubt any of them would take offense to the term. Surgeon was a remix artist before anything else, so it truley is natural that his performances would evolve in this way. A guy like Sasha can't produce if it meant his hands getting chopped off, but give him the mastered source material and he'll be able to rearrange it, for what its worth he is a better Remixer than he is a producer or a DJ for that matter.
not only do i think the exclusion of beatmatching makes this new artform different and uniquely classifyable, but i also look at how i personally would use it. i've been revamping my own live set to also include loops/ snippets/ phrases and my own edits of other tracks (much of it ripped vinyl). So this turns my live pa into a live pa with other people's material as a backdrop. Does this make it a DJ set? Does this remain a 100% live set? nah, i think it enters the new are of Live Remixing.
great thread btw.
