If your name is Marsalis, there's only one natural creative outlet: Jazz. It almost seems that the family patriarch, pianist Ellis Marsalis Jr., was grooming a band — Branford on saxophone, Wynton on trumpet, Jason on drums and Delfeayo on trombone. But as acclaim and attention has been heaped upon the personable Branford and the militantly outspoken Wynton, Delfeayo has established himself as a gifted musician (on just three albums with a fourth in the wings) and a visionary Jazz producer.
