7 x 7

Recently I found this short video on YouTube, with these words:
"This is the trailer for the film that French director Pierre Maillard is currently shooting about 7x7, the most amazing adventure in Art and Music. Robert Wyatt, Archie Shepp, Nile Rodgers, Sean O'Hagan, Mulatu Astatke and Kassin have joined forces with Belgian artist Jean Pierre Muller to reinvent the notes of the scale and the colours of the rainbow...".

Please check out a blog post from August 2012 on the same project, and do watch these videos too (Archie Shepp, Robert Wyatt).
