Thank you Sir Richard Branson for Virgin Classics (and Virgin Venture). Truly, in my honest opinion, the best classical label there ever was.
So, listening to Haydn myself: Cello Concertos under the direction of Iona Brown, featuring Truls Mork, Virgin Classics, 1991.
Earlier, Haydn, Sonatas Nos. 33, 38, 58 & 60. Emanuel Ax. CBS Records Masterworks, 1988.
One of my favorite classical pianists, alongside Glenn Gould and Jean-Bernard Pommier.
