My band just played our first weekend club gig last weekend and the response was fantastic. We were stoked that people liked us so much. Our next gig was scheduled at the same club the last weekend of the month. Well, on Wednesday I receive a call from one of our guitar players and he tells me we have a gig this weekend at another club in a neighboring town. My reply was " You know I have to work nights this weekend!" to which he replied, " They called ***(our singer) and said they needed a band this week and they had heard about us so I told her to tell them that we'd do it." I asked him what he would do about a bass player and he said they would get someone to fill in for me. I told him they should tell the club owner thanks for asking but one of our band members can't make it. Background: All of our band members have normal day jobs except for me. I work rotating shifts(days and nights) and we're open 24/7. The pay is good, however. When we formed this band from two bands back in April we were going to try and play two weekends a month and try to work around my schedule. We all have decent jobs and aren't really doing it for the money. Well, I knew there was one scheduled weekend in October that I probably couldn't make so while I was on vacation last month the band had two bass players come by to a practice. I know one of them but never met the other. Back to the story: The guitar player tells me that the bass player that I know is out of town so he'll call the other one. Then he asks me if the guy can use my rig for the gig! I told him absolutely not! I don't know him. If he's good enough to play he ought to have his own rig. I'm sure the guitar player thinks I'm being a jerk. Oh well. My two concerns are this: From a business standpoint, we're trying to get exposure and they want to do gigs with a bass player who doesn't know the material that well and that they're not used to playing with. From a personal standpoint, It's going to kill me to think about my band being on stage without me. I've been playing with 2 of these guys for 10+ years and the others fo 8 months. We have a great playing chemistry that Is rare. Am I wrong to be upset about this?
