Having proven himself by earning a seat with the best players contemporary jazz has to offer, tenor man Stephen Riley has already solidified his credibility. The 29-year-old spent time with the Lincoln Center Jazz Orchestra and the Mingus Big Band, and just signed a fresh contract with SteepleChase. Riley, a native of Greenville, N.C., will be at the ArtsCenter in Carborro this Saturday accompanied by bassist John Brown, Russell Lacy on drums and pianist Gabe Evens. Tickets are $14 or $12 for students; the show starts at 8 p.m. Visit www.artscenterlive.org.
