Jazz drumming is Ernest “Rip” Patton Jr.’s passion. He was preparing for a professional career as a student at Tennessee State University when something else happened in 1961 — something that took precedence. Patton became part of the civil-rights movement and was one of the Freedom Riders who boarded a bus for Jackson, Miss., to protest interstate and regional segregation and discrimination. Unfortunately, Patton subsequently was among 14 TSU students expelled for his participation, in addition to being arrested and jailed. But he did eventually have a successful career as both a jazz drummer and an interstate truck driver. Now having been honored around the country for his role with the Freedom Riders — including getting an honorary doctorate from TSU — Dr. Patton will combine music and history tonight in a very special program at the Nashville Jazz Workshop. “A Dream Re-Awakened: Geary Moore With the Freedom Riders Featuring Dr. Rip Patton” spotlights a group led by recently relocated guitarist Geary Moore. Besides teaching for five years at the Jazzmobile in Harlem, Moore’s three-decades-plus career includes stints with Jimmy McGriff, Slide Hampton, David “Fathead” Newman and Lonnie Smith. The band also features bassist John Birdsong and pianist Joe Davidian. Patton will speak about the Freedom Riders and their significance prior to the concert.
