WDNA-FM (88.9) Distracted by beautifully moving bodies at dance clubs, many people easily forget that a great deal of today's popular Latin music has roots firmly planted in the jazz tradition. Thanks to a clever mix of old and new, Fusión Latina primes even the untrained ear to make the essential connection between today's pop salsa acts and the days when jazz artistry infiltrated the folksy music that originated in the Caribbean. For two hours (8:00 to 10:00) every weeknight, various hosts present some of the hippest and coolest sides of Afro-Cuban, Puerto Rican, and other variations on a Latin jazz theme.
