I always think every time I go out I’m “in the studio”.
same here....
i love the studio, more than live honestly. I still sometimes get "red light fever", but mostly, i love hearing the raw stuff that is rough come to life. I also negate the red light fever by getting there early, and asking to help set up. I am the guy who is at every session....I love the whole process
and it definitely helps to do rhythm tracks "live".
what I would tell you is - like Bo said - to treat every time you play - even practice at home - like the tape is rolling.
Use a met/click all the time
Be able to play the song structures by yourself, while the music is going through your head. I have done many projects where I was the only one laying drum tracks, and I had to "hear" the other parts in my head while recording.
Write out a phrase chart.
Arrange some rehearsals where it is just you and the bass player, or you and the guitarists....isolate things down to make sure you all know who is doing what.
Make sure that song structures are solid before going in.
Don't make "game time decisions" about parts you have written; the studio is the worst place to rethink things
Don't leave anything to question once the red light is on.
Make sure that your equipment is in the best shape it can be, including no squeaks in hardware/pedals.
NO SIGNIFICANT OTHERS or non-bandmate friends. I can't tell you how many times things went downhill when people were in there when they shouldn't be. Often times the engineer will tell riff-raff to go hang in the lounge....
Don't let people force you into takes that you know are going to be worthless. I have had a few "producers" tell me to do it again, but with more
passion man .... if you have prepared well, natural "umph" will come out. 4th or 5th takes - at least from what I have experienced, are just wastes of time.
Be ready to be asked if you can move things a little bit to accomodate microphone placement, but in the same way, don't get talked into thigns that will pull you out of your comfort zone. The engineers job is to get your best take and performance...NOT to try out his new gear, or to make you play the way they would have
in the same vein, let them work their magic as well. I have had many times where I got to a studio and instead of using my drum set, we used some beat up, old war torn set....that sounded AMAZING
DEFINITELY go into the control room to listen to takes; I would also be wary of having "too many sets of ears" in the room when you do this. While I respected my bandmates decisions, I usually only had the engineer and my bass player listening to takes. After I sifted it down to one, then everyone else came in
there are tons of other ones as well, but these - for me - are sort of the foundational ones
