Actually this bring up something that was discussed during the last Pensado's Place episode (in chat), in that where is the line between mixing engineer and producer and should it be crossed if its not requested. What was brought up is that almost all the contests on indaba turn into dub step "re-mixes". When someone gives you a song to mix, SHOULD you take it upon yourself to make drastic changes in the production of the track, or just mix what is given and make the existing tracks as exciting as possible without re-writing parts and drastically changing timbres. I know if i sent out a rock tune to be mixed and I was returned a techno song, i'd be a bit irked, especially if it wasn't discussed. (not saying thats what YOU'RE doing) but just talking about "mix engineers" (and i use that term loosely) in general that think they're the next great producer. Im all for making things sound better and more exciting, just not too sure where to draw that line... what do you think?
