I wouldn't worry about her not talking to you anymore. The worst that could happen is you end up in the "friend zone".
Though it shouldn't be that hard to know if a girl likes you (unless you're totally smitten yourself--love is blind, in more ways than one).
p.s. Also, it might help if she's also a band geek.
