San Francisco’s DJ Ferrari, a Silicone Valley executive by day and über-collector by night, provides an outstanding Afro-Brazilian mix for the first hour and a half of the show. Even jaded Brazilian collectors will appreciate the intelligence and deftness of Ferrari’s mixing. Hour two--what there is of it--features eastern jazz, some funk, the obligatory Cuban track, and another brilliant cut from Augusto Martelli’s “Black Sounds From White People”.
