So I play keys in this classic rock/soul band. We normally play 2-3 gigs a month but we've had a break with no gigs in January and February. So we're using the opportunity to learn new songs and relearn old songs that fell off the set list ages ago. After we're done playing, the bass player expresses his frustration that people aren't learning the songs well enough in advance. (I'm guilty of just forgetting we're supposed to learn a song and not listening to it at all, and I admitted as much.) He gets louder and louder about this, ranting for about five minutes and swearing. Eventually the drummer and de facto band leader -- having been prompted by bass player to speak instead of "pouting in the corner" -- vents back about Bassist's antisocial behavior, and how tired we all are of having to watch what we say for fear of offending him as he has a record of blowing up about stuff and threatening to quit. Drummer gets loud also and goes on for a while. The rest of us are calm and trying to get both of them to calm down also. But the upshot is bass player very officially quitting. After bassist is gone, the drummer asks a couple of us left about cancelling our gig in 5 weeks. HOWEVER, both myself and the percussionist/backup singer play bass just fine. Percussionist has been learning bass parts for our songs for a few months since our bass player's last threat to quit (over different issues). I haven't been learning the bass parts, but playing keys I'm aware of all the chord changes and structures of the songs. so options 1) the percussionist and I split bass duties -- I play bass for songs that don't really need a keyboard part 2) we call up the band's previous keyboard player (who left 2 years ago) and revamp our set list to do songs he knows 3) The percussionist plays all the songs he's learned on bass and I attempt the dreaded "keyboard bass" on others 4) find another bass player entirely to play the whole night (I know several but they're on the other side of town, and probably demanding more than the paltry sub $100 per person pay we make for a gig.) 5) carrots No, I don't consider reaching out to our old bass player and making amends an option. I'm not mad at the guy, but I absolutely won't be in a band with him again. Anyway thanks for reading this far and I welcome everybody's input on where to go next.
