I'll be there and am very much looking forward to it!
Re: Metro. I've attended many, many concerts at the 9:30 Club and I've almost always taken the Metro. I've never had a problem walking to or from the Metro station. It's only about a block away and lots of other club patrons will be walking in the same direction. For what it's worth, most of the concerts I've attended at the 9:30 Club have ended closer to 11:40 than 11:30. The last Green line train to Greenbelt is ostensibly at 12:21am, but it's almost always about 5 minutes late. If you're going towards Greenbelt, you should haven't any problems at all catching the Metro. Indeed you'll probably end up waiting at the Metro station about 20-30 minutes, so you might want to bring a good book. If instead you need to catch the Green line train to Branch Ave. in order to transfer at Chinatown or L'Enfant Plaza or Metro Center, for example, then you need to be a lot more careful. You might want to skip the last song of the encore, for example, or at the very least move closer to the exit and be prepared to sprint to the Metro station. I think the last Branch Avenue train is at 11:48pm (double check the Last Train sign at the Metro Station before you leave!), but it's often a couple minutes early. I usually see a half dozen people or more get stranded at the Metro station following a 9:30 Club concert nearly every time. Moral of the story: If you're coming to DC from out of town and then taking the Metro, park at the Greenbelt station instead of some station on the Red or Orange lines, for example. See
