Pictures at an Exhibition
Modest Mussorgsky's biggest hit wasn't a hit at all, as far as he knew. Mussorgsky wrote Pictures at an Exhibition as a work for solo piano. It wasn't even published until after his death. He had no way of knowing that his quirky piano piece would turn out to be one of the greatest orchestral hits of all time, thanks to Maurice Ravel and a host of other composers who've made orchestrations of it. The Vienna Philharmonic plays Ravel's version, in the Gardens of Schonbrunn Palace.
