Saw them at the Borderline in London last May (same week they were on Jools Holland). Cracking gig, very lively. They were supposed to play a couple of festivals in UK/Europe as well last summer but they were cancelled, - not sure why, but they seem to have been touring constantly in the US over the past year so maybe they've decided to focus their efforts there for the timebeing?
Hope they come back over here - would definitely recommend seeing them if/when that happens.
