I never used to like recording. Most studios I knew were underground, because it was easier and cheaper for the soundproofing. I used to come out with a ringing headache from the lack of light and the strain of trying to achieve simple accuracy. Practising with a metronome beforehand can save a lot of time and frustration in the studio - for you and the techs. You need them on your side. The best advice that has come up here so far though is to do it with friends. If you and the studio people get on with each other the time will go by much faster. Good luck. Alan.
