Tonight, before going to sleep, I'll be rehearsing for a performance of Mussorgsky's PICTURES AT AN EXHIBITION, which is a dream come true for me. It was written for piano, though Ravels's brilliant (however flawed) orchestration is far more commonly heard.
Here is an odd take on "The Old Castle" by Sissel, that I just stumbled across. After one listening, I'm not quite sure what to make of it.
It does tie things together rather neatly, though.
And here is closer to what Mussorgsky had in mind.
And here it is in Ravel's colorfully dreamy orchestration, with a rare symphonic use of an alto saxophone.
