Thankfully as expected, footage from Jawbox's performance last night is now online. (Here's one of many sites that have the main clip, along with songs from soundcheck.)
As somebody who never saw Jawbox play live, this was quite a great performance. Keep in mind, I have no frame of reference of how they played between 1989 and 1997. So as somebody who saw J. play with Burning Airlines twice, has listened to the band's discography since 1996, and oh, wrote a whole chapter devoted to them, I'm very safe to say that I'm satisfied.
Not to be one of those annoying folks that wants bands to stay together forever, but I hope this wasn't the last we've seen of a Jawbox live performance. I definitely do not think these guys should give up what they've done since the band's breakup in 1997 and tour like maniacs. Rather, one-off live shows would be great, but I don't call the shots on that.
