I'd have to agree with dr. doom. I've been going to shows in the area for roughly 10 years, and it used to be that you had to regularly attend shows at the black cat or the 9:30 to know who was playing, or check the listings in the city paper to be up on stuff.
Now, just a few clicks on the computer and you now what is coming up, plus you can buy the tickets online as well. No more treking to the box office or a ticketmaster outlet, or whatever.
Between the websites kosmo mentioned, the bands' sites, etc., it is just easier to get the information.
Just a question - is this a good thing in a way? I mean, if the 9:30 can virtually guarantee a sellout to even a moderately well known band, is it more likely that bands will stop through dc to play? Which would benefit the fans. Just a thought.
