You've got to love the BBC. Any broadcasting system that shines a light on their native composers and artists has got to be commended. America's public television has done this as well, but you don't seem to see this anymore. I'm not sure why, but I find myself going to YouTube much more these days in search of musical nourishment than my TV.
This documentary refers to Eno as an "intellectual guru." I would take slight issue with the word intellectual in the pejorative sense. If you mean he's a fascinating man who thinks (dreams) about new ways to make music and art then I agree. But Eno's process doesn't end with his mind-he listens and trusts his instincts.
To be honest, the best composers have always done this.
Brian Eno is one of the most interesting and thought-provoking composers of our time.
