Last night's open mic was a combination of humiliation and success. If I can derive some of the latter to go with the former, it's progress. I'll tell you what: it's far easier sitting in your house playing the guitar/singing that in a dark bar up on a little gnarly stage in front of a room full of half drunken bumfarkers. Mainly because the song we were playing was one me and this woman had rehearsed for 10 mins in a rainy parking lot. Later I was just playing the guitar with some guys up on stage and then I got to lead the band and sing on a blues standard I'm quite familiar with and that last number was the one that went well. Getting more confident in my lead guitar playing, which really makes it a blast.
I greatly prefer playing to the singing/playing, but it's the singing that may help land me in more playing situations, so sing I must.
