The Fratellis (photo: Ria Burman) The Fratellis opened their sold-out show with the bouncy, beaty tune, "Henrietta" Monday night, delivering a most welcome flashback to my 20s. What followed was a collection of new and old songs of get-up-and-move grooves. The Fratellis brought funky, fun, and fresh to the Fillmore for a rocking-indie, good night.
