Hannibal Lokumbe is not caught up in what classical music “should” be. He composes for symphony orchestra, and improvises on the trumpet. He plays in concert halls, churches, and prisons. On his visit to Nashville the main event was a performance of his massive piece Crucifixion/Resurrection. But Lokumbe also made time for public speaking on the topics of mass incarceration, the spiritual existence of people of color, and the life of Fannie Lou Hamer.
