The 1960s saw political turmoil and upheaval across the world from the Civil Rights movement in the US to independence struggles throughout Africa and student uprisings in Europe.
While these events unfolded, a new sound ignited jazz.
Known as free jazz or simply, the New Music, it saw artists release themselves from the constraints of melody and rhythm in favour of energetic and at times volcanic expression.
As well as developing 'New Music' some players also adopted a DIY approach, forming independent labels, finding new venues and founding collectives such as the Jazz Composers Guild in NEW YORK and AACM in Chicago.
In the subsequent decades organisations such as DAAGNIM would also spring up and in Britain we saw the Jazz Warriors and more recently F-IRE.
To what extent do these collectives uphold the revolutionary spirit of their '60s forebears? Have they found the ultimate artistic and political freedom?
