Judging only by the few clips I have seen from the London production and the promos with Grammer, I would have preferred for the 2005 revival to have been recorded. It was just a louder and more polished sound. Not that and less polished, smaller sound isn't suitable, but the OBC recording is low quality and difficult to hear those great orchestrations. The last revival would have been brought today's great sound quality to it.
But what's in the past is in the past and I would LOVE for this upcoming revival to have a recording!!!!
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
