What was once a Vancouver institution is returning this year, with a twist: all funds from veteran percussionist Sal Ferreras’s Drum Heat will go to benefit Arts Umbrella. What hasn’t changed is the event’s wide-open approach to the percussive arts: tabla virtuoso Cassius Khan and Brazilian chameleon Celso Machado are among the drummers who’ll assist Ferreras at the Vogue Theatre on Thursday (April 27). But Drum Heat is about more than just hot beats: also joining the crew are the Sarabande youth choir, mandolin master John Reischman, and an assortment of fine local jazz performers. A good time is guaranteed.
