I am at a crossroads. My drummer and I are friend, but I have been talking to him about his playing for a few months. He doesn’t know the songs a lot of times and his tempo is on and off. I’ve worked with him one on one, but that has gotten on my nerves because he comes over but doesn’t know the songs. At first I’ve been PC about it saying stuff like we and not point the finger, but it hasn’t worked. About two weeks ago I let him know he had to do better, meaning know the songs. Well he was really off this weekend on a big gig. My singers called me the next day complaining. I know I have to do something, but I’m not sure if should give him a ultimatum of get right I make a change, or just cut musical ties and move on.
