I play in a band with two guitarists, a drummer and a singer. We practice one night a week for 3-4 hours. We've been playing together for a couple of years and we are all older guys 30's -50's. We all have pretty demanding jobs, and at times can't make rehearsal. Well we usually just can it for the week if someone can't make it and try again the next week. Well lately we have missed a lot of practice. What do you guys do when someone in the band can't make rehearsal? I figure that my options are 1) rehearse with the remaining members, 2) look for a fill-in for the evening or 3) do like we have been doing and just can it for the week. Any input would be appreciated.
