In a HardTalk Extra interview screened on 6 January, Noel Thompson speaks to one of the greatest living jazz musicians, Herbie Hancock.
Herbie Hancock has been pursued by the "jazz police" for much of his career
For forty years Herbie Hancock has been pushing the boundaries of jazz to the delight of many - but to the horror of the so-called "jazz police".
He looks likely to upset them again with his latest album, Possibilities.
He talks to Noel Thompson about why he chose to collaborate with new artists like Christina Aguilera, and why he first came to fall in love with jazz.
