Mussorgsky’s Pictures at an Exhibition in its original piano version (written in 1874) is certainly one of the most-recorded of all piano works, with hundreds of different pianists having a go at it (some of them several times). The list is updated on an occasional basis.

Mussorgsky’s Pictures at an Exhibition is surely the most-arranged piece of classical music. There are many hundreds of arrangements known to me, for almost every conceivable (as well as a few inconceivable) instrument or combination of instruments, and well over a thousand recordings of those arrangements (many of which have never been recorded). The list is updated on an occasional basis.

Mussorgsky’s Pictures at an Exhibition has inspired many composers in their own works, and the list here shows those that I know of. These works either quote bits of Pictures or are influenced by it in some obvious way. The list is updated approximately on an occasional basis.
