Two of Karajan's bestselling recordings with great soloists. Karajan's rare collaborations with Soviet musicians in the 1960s resulted in exceptional recordings that have become classics - including the ones presented here: "a performance of astonishing intimacy and refinement" from Richter in Tchaikovsky's First Piano Concerto (October 1962), and "a deft and stylish account" of the Rococo Variations with Rostropovich (September 1968) Citations from R.
