Its tough, there are so many bands, so many people, but ironically, sometimes hard to find people you know who share the same interests in music!!
Speak progressive, hard rock and alternative, and there goes half the female group. Speak emotional lyrics, controversial bands and there goes the christian/religious group...etc (I'm being stereotypical here)
FOr me, just enjoy the music, enjoy the art, learn many instruments and wait and see if the "band" opportunity comes along....if not, juz create your own opportunity and take the initiative and go recruit your own.
