The band that I'm in has two members who rarely practice with the band. They do show up to play the shows that we have, 1 guy for the most part knows what he's doing even without practicing with the band much. The other guy is hit or miss at the shows and yes the band has talked about getting both of them to practice more with the band. Also when these guys play a show that's what they do theyBa play and leave, no helping with setting up breaking down etc.. Does anyone have experience with a situation like this? If so what did you do? I just don't consider them fulltime "band members".
