It isn’t easy being a standard bearer. That adage is especially true when your peers seem to pass on suddenly. Such is the case with the legendary bandleader Eddie Palmieri. In the past few years the world of Latin Jazz and salsa have lost Tito Puente, Mongo Santamaria, and most recently Cuban diva Celia Cruz. But Palmieri presses on, earning a Latin Grammy nomination for last year’s La Perfecta II and releasing his new album Ritmo Caliente (both on Concord Picante) this summer.
