Christian McBride can be likened to a force of nature, fusing the fire and fury of a virtuoso with the depth and grounding of a seasoned journeyman. With a career now blazing into its third decade, the Philadelphia native has become one of the most requested, most recorded, and most respected figures in the music world today. Raised in a city steeped in soul, McBride moved to New York in 1989 to pursue classical studies at the Juilliard School. There he was promptly recruited to the road by saxophonist Bobby Watson. Call it a change in curriculum: a decade’s worth of study through hundreds of recording sessions and countless gigs with an ever-expanding circle of musicians. Currently he hosts and produces “The Lowdown: Conversations With Christian” on SiriusXM satellite radio and National Public Radio’s “Jazz Night in America.” South Motors Jazz series subscriptions are $155 and $180; in advance single tickets $35 & $40; day of concert tickets $40 & $45.
