Every spring, RJ Spangler's Planet D Nonet (PD9) pays tribute to the originators of swing and jazz with a concert at Detroit's Scarab Club. This year, PD9 will feature the Kings of Kansas City Swing: Bennie Moten and Count Basie. As a prelude to the May 21 event, PD9 will be presenting a free workshop and concert featuring two students selected to sit in with PD9 as they rehearse tunes for the Scarab Club performance. Benny Rubin, Jr., alto sax, Detroit School of Arts and Tariq Gardner, drums, Jazz Studies at University of Michigan. Spangler saw both of them performing at Bert's Market Place Jazz Club in Detroit and decided they were the perfect young musicians to whom to pass along the music of the past.
