Fascinating, arty documentary about and by Daniel Lanois, the yang to Brian Eno's Yin. He was the musicality in Eno's ambient experiments. He's produced the best stuff from a variety of artists from U2's Joshua Tree to Emmylou Harris's Wrecking Ball. Peter Gabriel's So to Neville Bros Yellow Moon.
As with many genius types he can be as off-putting as awe-inspiring, possessing a gentle arrogance.
