He's an NEA Jazz Master and a Grammy Award winner who has recorded with everyone from Miles Davis and Sonny Rollins to Sting and Bruce Hornsby, but saxophonist Branford Marsalis' musical credentials are perhaps best expressed by his last name, which he shares with legendary father Ellis and musician brothers Wynton, Jason, Ellis Jr. and Delfeayo. The New Orleans-based family's influence on the last half-decade or so of jazz cannot be overstated, and Branford's current quartet, which features pianist Joey Calderazzo, bassist Eric Revis and drummer Justin Faulkner, continues to explore the contours of the all-American genre to invigorating effect. After Sunday's 3 p.m. concert on campus, Marsalis will deliver the E. Paul Torrence lecture on creativity in the first-floor auditorium of the Georgia Museum of Art. The 7 p.m. lecture is free and open to the public.
