With this year's musical guests including the Matt Full Band, the Frank Russell Quartet, and Davenport phenom CJ Parker, Polyrhythms proudly presents the 11th-annual Bill Bell Jazz & Heritage Festival at Rock Island's Martin Luther King Center and neighboring MLK Park, an August 22 through 24 celebration of cultural heritage in the Quad Cities named after the late musician, educator, and East Moline native lovingly known as “The Jazz Professor.”
