The Galactic offshoot band, which features guitarist Jeff Raines and bassist Robert Mercurio now plays more often in New Orleans than their main group.  After last night’s free show at Tipitina’s, which was marred by horrible sound (the second time I have observed this problem in the last couple of weeks), they return to their stomping grounds on Frenchmen Street.  With keyboardist Joe Ashlar out of town, the stellar Brian Coogan rounds out the band with drummer Simon Lott.
