Haydn piano sonatas - Leif Ove Andsnes 

That's arguable. This piece is exquisitely rendered by Ove Andsnes, but not something I would return to for repeated listening.

@@dvdgrog I havent said "the best piano piece ever", but "the best piano composer ever". The reason is plain, consider him in his historical context and that what he achieved and his everlasting transcendence. All composers after him have used more complicated technique perhaps, but not more quality music.

There is no need for playing it slower either. I find this refreshing.
