I heard of the mixing backwards thing before (reverse all audio yeah? then reverse the mixed track the original direction?) its supposed to give a detached perspective to levels and the attack of compressors act as releases and vice versa with extra control of peak levels. I've done the re-amping thing (Sounds like synths on Nitzer ebb -Showtime) although i'm too lazy these days.two oh one wrote: Mixing an entire track worth of stems backwards.
Re-amping synths in a nasty sounding bathroom.

Sending a mike to a reverb or fx and then playing a track your working on and moving the mike around the room, towards/away from the speakers can be a fun way of adding reverb, just mute the fx output so you don't get feedback or use the feedback as an effect in itself.
