I've watched this thing a bunch of times and the sound quality,picture quality,liveliness of the band and the music is incredible.
The Dresden Dolls is just 2 people ,Amanda and Brian.She plays piano and he plays drums.
They describe their music as punk cabaret. It's rowdy,sexy,gross,sensitive,fun..pretty much everything and they have street type performers at their shows doing acts while they play.
Highly recommended.I picked it up at HMV.
Here's an amazon link.
