Why ‘Edge of Jazz’?

Trying to define jazz in the twenty first century is impossible. Like most other musical forms it has fused and mutated into many different shapes and styles which now defy any form of categorisation. So rather than answer the question “What sort of music gets played on the show?” it’s easier not to attempt a single answer and simply reply ”It’s on the edge of jazz!”

In any case the presenter has a predilection for what used to be called “Soul”, “Deep Soul” “Blues” and that much maligned term “R&B”. The show also features fusion, electronica, nu-jazz and whatever other new categories emerge to try and define “Jazz” Without apology the show is about what the presenter wants to hear and listen to, and perhaps most of all, enjoy!

"There's something decadent and indulgent about listening to two hours of excellent jazz on a Tuesday afternoon"
