Ok, this was probably the most fun gig I've ever been to, both in terms of the performance and the setting.
It was in a clock tower in Hackney and they did a 'song' on each floor of the tower, finishing on the roof. It was a really nice atmosphere and it worked very well.
They did about an hour of acapella, almost formless stuff and I didn't get bored once. Contrast this with most other bands' sets, which I tend to start hoping will end after about twenty minutes. They're very inventive and playful.
More bands should be like them.
