In this final episode of Jazz Junctions, trumpeter Guy Barker examines recent junctions in jazz and considers where the music is heading in the 21st century. He looks at the impact of advancing technology, institutionalised jazz education, and the increasing influence of traditional music from around the world. Is jazz still developing or is it now static, with the old styles constantly being replayed? Guy Barker investigates recent jazz and looks to its future, with the help of musicians Roy Haynes, Terry Gibbs, Kenny Burrell, Albert 'Tootie' Heath, Wayne Shorter, Evan Parker, Ed Shaughnessy, Peter Erskine, Billy Taylor, John Scofield, Eddie Bert and Robin Eubanks as well as critics Ira Gitler, Bruce Boyd Raeburn, Dan Morgenstern, Scott Yanow and Ted Gioia.
