I find it astonishing, really jaw-dropping, that Midge Costin’s mainly enjoyable Making Waves: The Art of Cinematic Sound (2019),available on aUK DVD on the Dogwoof label, can seemingly base much of its film history around a ridiculous falsehood: the notion that stereophonic, multi-track cinema wasinvented in the ’70s by the Movie Brats—basically Walter Murch, in concert with his chums George Lucas and Francis Ford Coppola—finally allowing the film industry to raise itself technically and aesthetically to the level already attained by The Beatles in music recording.
