Ok, this can be discussed without going into the actual beliefs that cause friction, so let's not go there: My old friend has connected with a great singer/songwriter and they are forming a project. I love the genre and he said he wants me in this band, so we've been discussing plans. My friend came to my house for dinner and to discuss, but conversation took a sharp detour into the political zone...BIG time. Before long, there was yelling, insults, my wife had left the room and took my kid with her, and I was close to asking him to leave my house. Really bad scene and the night ended sourly. We texted the next day and smoothed things over, but this kind of discussion has been happening more often with this friend (although not this heated). Now I don't know if I want to put in the time to build a project just to find out we're not going to get along. No problems with the musical vision, but I don't know if we're asking for trouble. Have you ever refused a band offer or quit a band because of this kind of thing? What has been your experience?
