I know. I've been waiting to see Elf Power (I only have one album, "Nothing's Going to Happen," and I like it, so would love to catch their show and see if I should get more...), and was pretty excited when they were going to be at DC9 -- which means finished by 11:00 or so.
But that late on a weekday is nigh near impossible; I don't mind weekday shows (in fact, there are often fewer social conflicts to deal with during the week), but I've got a job. And I actually have to be alert (hell, I'm angling for a pretty intense promotion, I need to be more than alert, I need to be downright perky...).
In the extreme, I can see four bands on a weekend night (and at a place like 9:30, they'd start by 8:30). But, like you B.C., I'm almost certainly going to miss the first two bands unless I hear some real, specific positive buzz on them.
Well, at least I can dedicate my time to the Sox tonight...
