San Diego turned out to have room for exactly one night like this: a live band working Funkadelic, Sly and the Family Stone, and Earth, Wind and Fire deep cuts without apologizing for the format. House of Funk has made it a monthly residency at Music Box on Saturdays -- the same group, with rotating singers and horn players who know the catalog by heart. August 8 is the next one. Five hundred capacity, downtown, doors at eight and music at nine, twenty dollars at the door. The crowd is the SD funk faithful -- the people who own the original pressings and the people who learned the catalog from them. By Saturday night, dancing breaks out and the bar staff knows to clear space for it.
