9:30 Club is a Washington DC venue that has plenty of metal shows. I picked this set of 3 buttons up for $2 at the Queensryche show a couple of weeks ago. If anyone wants a set, let me know and I'll snag a set the next time I'm at the venue. I wish more places would do this sort of thing. It is cheap and easy and us crazy tshirtslayer types tend to like this shit.
