TO A YOUNG JAZZ MUSICIAN: Letters from the Road

America's foremost jazz classicist assesses the state of the art in this impassioned epistolary manifesto. Marsalis, now the artistic director of Jazz at Lincoln Center, answers critics who denounce him as the "gatekeeper" for a fossilized middlebrow establishment with a spirited defense of standards against both post-bebop modernist abstraction and the contemporary trend toward promiscuous fusion with other pop styles. As conservator of the Armstrong-Ellington legacy, he champions a jazz grounded in melody, blues, romantic feeling and, above all, swing rhythm—a "democratic, quintessentially American concept" that "channels the spirit of the nation." He urges young musicians to take their art seriously through constant practice and a stern work ethic: "practicing is a sign of morality in a musician." Marsalis and amanuensis Hinds (Gunshots in My Cook-Up ) sometimes sound like a motivational tape ("unleashing your personal power is the result of codifying... your own hard-earned objectives"), and their occasional mystic invocations of musical self-discovery and "the emotion of the sound" can confuse. Also, Marsalis's jazz traditionalism shades, at points, into a jeremiad about modern "decadence" and "corruption," inveighing against what he sees as our culture of absurdity, with its sexually precocious children and jeans-wearing jazz men. But musicians, aficionados and casual listeners alike will enjoy this lively polemic. Agent, William Morris Agency . (Oct.)
