My column in City Arts highlights the 40-event Central Brooklyn Jazz Festival, taking place throughout April “from Flatbush up Fulton Avenue through the neighborhoods of Fort Greene, Clinton Hill, Bedford-Stuyvesant and Ocean Hill to Bushwick . . . the area that gave birth to Max Roach and Randy Weston some 80 years ago.” It’s booked with lesser-known yet highly active African-American jazz musicians; on Saturday I talk about “Where is Jazz Going?” at Medgar Evers College (2 to 6 pm) in distinguished company.
