A master timbales player, Sammy DeLeon has appeared in New York, Chicago, Miami, San Juan and many points in between. Formerly the musical director of Impacto Nuevo, he's led his own group since 1996. Equally adept in Latin jazz, salsa and merengue, DeLeon is a local treasure. Tonight at 8 at Market Garden Brewery, this local Latin jazz band plays a special concert to celebrate spring. Tickets cost $15.
