Some of the best and rarest of Ken's work is about to be released on DVD. The films are The Debussy Film, Dante's Inferno, Always on Sunday, Isadora: The Biggest Dancer in the World, A Song of Summer and the very rare Dance of the Seven Veils. These are works Ken did for the BBC.

It is a USA release and seems to have got round the Strauss estate embargo on Dance of the Seven Veils. The release date is 23 Sept 2008. Thanks to Michael for the info.
