Thanks to ItsJustDave for the original reminder!
9:33 PM EST EDIT: Show's over. I'll throw up a link to one of the recordings/podcasts once they're made available. It's worth noting that about 150 people showed up live for this and all of the listening slots online filled up quickly. Very cool.
ANOTHER EDIT: And here's a link to an mp3 of the performance, courtesy of ItsJustDave. Click!
