My drummer has decided he can't be bothered to come to practice any more. Whenever we get a practice time sorted out we ask him if he can make it, he says yes. Then as we're all set up, we get a message saying sorry guys, I can't make it. Also, as we have secured our 4th singer, we can finally get on and write some good s**t and record it, gig, and most importantly, play. Does anyone else have a similar problem? How can I persuade him to come to practices or do I need to give him the boot?
