If you really want a band, you just gotta make an effort to find people. I don't have a singer (you cant be good at guitar and vocals, i'm positive:) but i'm sure theres plenty of people wanting to play in a band. I met some kids from my friends old school, and wouldnt you know, almost every one of them plays an instrument and doesnt have a band. You just gotta be on the lookout, and you will find people, its just a matter of time. And what was recently said about playing with people better than you. That is a very good point. I have guided my friend in some guitar playing, and his improvement compared to others is tremendous. Having someone who knows what there doing can be very key.
