Wolf Harden is the soloist, with Heribert Beissel conducting the Slovak Radio Symphony; from a Marco Polo recording. In my library are Walter Gieseking’s 1943 account and a cpo release with Volker Banfield at the keyboard and Werner Andreas Albert leading the Munich Philharmonic. The latter disc includes a fascinating liner note by Hans-Christian Schmidt, with liberal quotations from Wolfgang Rihm’s essay “Zur Aktualität Pfitzners,” which states, among other things, that Pfitzner resides in a “secure position of uncontested complete contestability.” One can scarcely argue with that.
