Music appreciation from Jonathan Demme

For some reason, I've never seen Philadelphia, and I also worked in the classical department of a record store in the years following its release (and therefore always needing to be able to hook up a customer with Maria Callas singing La Mamma Morta at any given time), so I was not expecting to be so blown away by this scene as I came across it in the Onion AV Club's appreciation piece for the late Jonathan Demme.
