Baz Luhrmann’s “Elvis”, like all of his films, is an audacious fusion of sight and sound, and Wayne Pashley, the owner/co-founder of Big Bang Sound Design, has been working with Baz for more than 30 years. Credited as the re-recording mixer, sound designer and supervising sound editor on “Elvis”, Wayne is uniquely qualified to talk about the “sonic glue” that helps hold the whole construct together.
