Last year our guitarist ditched us. It was in the summer. He told us he was coming up. Then he never showed up. Didn;'t answer his phone, IM, TXTs. Nothing. I got really mad at him. I would not talk to him all year up until last week. I started talking to him and we are cool again. Now his new band, the one who he ditched me and my best friend for needs a bassist to play a show at a well known place. National acts play here. They asked me if I was up for it. I have no idea of what to do. I dont want my band thinking I am ditching them. I explained that if I did this that I am not ditching them. Me and this guitarist are cool now, but like I said, we didnt talk for a year. What should I do?
