Musical difficulties - we can talk it out.
Won't talk - one of us walks.
Working with a drummer with issues can be a real drag, but I've gigged with some young guys who were open to learning some new things, and eager to pick up whatever tips they could from the... ahem... more experienced guys. This can be a great position to be in, mentoring a younger player. I'm not perfect either, and I've learned a heck of a lot from drummers I've worked with.
If the under performing drummer's attitude and ego suck, and I can't even talk to him, I'll do my darnedest to never have to work with him again. That includes giving my impression of his abilities and attitude to the person who hired us in the first place.
IMO that is the key... If the person.. whoever it is is willing to listen to advice and put some effort into correcting the problem I am all for trying to work with them.. but if they just refuse to listen or accept any kind of help/criticism that is another story. I guess it is a little different for me because I don't have to pay the bills with my playing (thank goodness or I'd be a hungry mo living in a box..
) and I am rarely in charge of the situation with most of my playing being done in church. We had a drummer who had a terrible sense of time. I got her a metronome ... on the DL of course and it helped.
