We're familiar with Shakespeare, and we know just how good Hamlet is. But this recording is all about the golden larynx of Richard Burton. As it was a recording of a live theatre performance, the sound quality is less than perfect, but who cares? It's a privilege to be able to listen to him. I agree with some that his Hamlet may be a little too manic in places, but maybe not an unreasonable interpretation.
And as a bonus, the honeyed tones of Gielgud feature as the ghost.
