DEREK BAILEY --ON THE EDGE-- FEB 1992. PRO DVD.
Presented by guitarist Derek Bailey and based on his book "Improvisation".
A series of four 55 minutes films shown on Channel 4 TV in the UK in early 1992.
To say this was the best and most intelligent analysis of improvisation to be screened on UK television is probably unnecessary: it has in all likelihood been the only televised programme on this form of music-making. Written and narrated by Derek Bailey, produced & directed by Jeremy Marr, it developed out of the first edition of Bailey's book on improvisation (the broadcast almost coinciding with the publication of the second edition) and attempted to provide a world-view of the subject, not being bound by country, musical genre or preconception.
