I've been playing/jamming with a drummer a lot lately while trying to find a few guitarists to start a band with. I understand that everybody goes through musical slumps, but he seems to not even be trying to get out of it. We'll play for maybe 20 min, and then he'll decide to stop, which drags me down too. He seems to be getting bored with his playing, but I can't convince him to learn any new beats or fills, even though both him and I know he needs to keep improving himself. Is there anything I can do besides try to find a new drummer? Id rather not if possible because he and I share a favored taste in 80's thrash metal that nobody else in our town seems to have. Your advice would be appreciated.
