So far I know of 6 people commited to come play. Skill levels range from "very serious and in a band" to "singing for the first time". Kind of a wide range of stuff is being played so far as well. Anything from SRV/Hendrix, to Chilli Peppers. The Beatles, Neil Young Pearl Jam, The Cure. etc.
Any kind of music is welcome. I think it should a be a really good time. The object is not to have a bunch of snobby musicians judging each other, but to just have a good time. I am even doing some lead vocal duties on 1 or 2 songs, which is a new experience for me. So don't be expecting perfection from anyone
