Blue Note records documentary on the iplayer.
music comes across beautifully, both present and past, good talking heads for the most part. And the graphics are beautifully done / highlighted with a very deft and light touch (e.g Francis Wolfe's photo contact sheets are often shown and then images 'cropped' on the fly into the final record cover artwork).
there is, for me, a slightly disquieting element in terms of cultural / ethnic identification (this content is debateable and implied rather than an explicit aspect - so don't be put off) - it would always be my hope that such things had long been transcended and the spirit (if not the music) of the 'fusion' of the 70s continued to prevail. But I guess with things 'as they are' in terms of Populist racism etc, it's hardly to be wondered at in terms of a defensive reaction.
