Heard some of this last night; a superb BBC documentary about Brian Wilson and some of his production techniques that shaped the Beach Boys' albums. Some great interviews, and lovely musical deconstruction of harmony and voicing. Obviously, as a "listen again" programme, it's only around for six days - so get listening!
