Don't fret girl. I don't know how old you are, but when you go to college, punk rock will find you, as long as you do enough drugs and sleep on enough dank floors of overcrowded houses.
If you're in high school chances are very few wil know or care about Sonic Youth Dino or pavement, so I'd suggest covering bands that are more current: No Age, LCD Soundsystem, Deerhunter... Then when people ask you what you're playing, you can at least point them to some albums that have been released in the last five years. But just keep the spirit alive and you'll eventually find what you're looking for in the end.
As for girls covering those bands, fuck yes!!!!
girls can do anything boys can do, except get decent jobs and achieve social status
