This weekend, Galactic will bring its current tour to a close with two performances at the Fillmore in San Francisco. On both Friday and Saturday nights, the Greyhounds also will be in town, performing at the Boom Boom Room. Each of the Greyhounds shows will feature ‘A Very Special Late Night Monster Set (After Galactic) with musicians joining Greyhounds.’ Galactic’s Robert Mercurio and Stanton Moore produced the Greyhounds 2004 release Liberty, so you can do the math yourself but it would appear that Mercurio, Moore and/or their band mates will head over to the Boom Boom Room after their Fillmore gigs.
