I went from "what the fuck is this?" to "you better fucking believe it!" once I remembered who this was. Some of the best parts of Mountain Goats shows is when John is talking. I am looking forward to some Ace of Base analysis.
Jet Age are fantastically energetic live. Check out the Pitchfork review of their album: http://www.pitchforkmedia.com/article/record_review/48695-what-did-you-do-during-the-war-daddy
Click the tickets link above to buy online (looks like they are still available). Not sure if you can buy at the door but you can get them at the Mercury Lounge Box office (212–260–4700) and not pay any ticket fees. (The Mercury Lounge is the box office for all the Bowery Presents shows, this one included.)
