The Untempered Schism, yes. Which, by the way, is a name I adore. Just in terms of how it sounds; it's a very aesthetically pleasing combination of words. I just forgot for a moment there whether that was actually in the show, or if it was a fanon thing I'd heard so many times I thought it was canon.

But ooh, I have to say, I love the idea of a Doctor with the drums. It intrigues me, very muchly. Though my Master... he's not quite sure what to make of it. Whether to go thank the gods, someone else can hear them too! or to be furious that it's no longer just him.
