It always helps to communicate. Like say hey, check it out, I think the record goes like this, then play your part while singing the drum part. Maybe he didn't bother listening to the record. I've done this from time to time, most recently on into the mystic. Guitar player/singer/BL says "but we don't do it like Van Morrison." Drummer says let's try it, then launches into it with a too-fast straight ahead rock beat. I try playing the part, it's not working, so when we're done, I say hey check it out, I think the record goes like this... Next take was better. Nobody's fee-fees were hurt.
Yep, communication is key. You can't be too frustrated until you know he knows what you're thinking. It's everyone's job to get on the same wavelength.
