This evening, you can still get your groove on at the Blue Nile, but it won’t be listening to the regular Wednesday act, Khris Royal and Dark Matter.  The saxophonist is on the road with George Porter, Jr. and his Runnin’ Pardners.  Groovesect is part of a new contingent of young bands that mine the funk territory of the Meters.  Upstairs at the Blue Nile, another young band, Gravity A performs.  Both shows start around 10 PM and there is no cover.
