I do a LOT of alternative. Me and guitar. Many songs mostly forgotten from the 90's, many newer and known by people who listen to the right station in the area. Not by design, these songs just work for my voice, and I can belt them out. As the night goes on, I transition away from that and toward just fun drinking/dancing songs. So far, it works. I've got a very light solo calendar and friends who come see me.
My worry is the sustainability if I ramp things up keeping this selfish approach to song selection. The self-doubting part says strangers in older or younger demographics than my mid-twenties sweet spot won't want to hear this stuff, or me belting it for three hours, and the other part says it will work if I own it and do it well. So I would like to know
