[font=trebuchet ms]The engineer is responsible for actually recording the tracks, usually under supervision of the producer. It can get really ugly if the producer (who may have stated out as a recording engineer) meddles too much in the recording engineer's work. The producer is responsible for managing and supervising, while the recording engineer and mixing/mastering engineer are the guys with the technical skills needed to realise the producer's 'vision' of what the result should be. It becomes obvious that there is huge potential here for conflict and power-struggles. With some of the egos involved, it's a wonder that anything gets done at all.[/font]
