So what do you prefer?? For me a radio show should reflect the scene's latest productions...so therefore the DJ has to drift a little bit out of his sound sometimes in order to play the newest releases...
A live set reflects a DJ's taste much more...he can play an old tune without any problem as long as it fits the set and the context (amongst many other things the DJ can do during a live set)...
So for me no question about it I'm a live-set fan...
How about yourselves??
