With Beirut's blasts of regal brass, that inspire foot-stomping and cape-twirling mariachi antics, you half expect Zorro to come dashing across the stage in all his sword fighting glory.
But no, there are few dramatics from frontman Zach Condon and his merry band of minstrels. About as wild gypsy wedding the Beirut lads get (apart from the drummer who is a smiley, rock-steady groover) is during the folky knees-up jam of the encore.
But while they could let loose a little more, they do what they do best and that's play their instruments. They are a clever and deft bunch of players on everything from the accordion and ukulele to french horn, trumpet, and tuba.
Condon, who has been playing his unique brand of elaborate, Eastern European-influenced folk music for six years now, and released three albums and a number of EPs, still has a bashful look of delight that he gets to play his tunes around the world for a job.
This show sold out so quickly when it went on sale last year that Beirut could have played two - or even three - nights at the Powerstation.
