thank you for informing me of the Lipatti performance of the Bartok concerto, was under the impression it was an unrealized project. you are probably referring to the recording from Baden Baden, 1948, with Paul Sacher conducting. Sacher was a close associate of Bartok. if you go the the site of the musicologist R.Greenberg, robertgreenbergmusic.com, he has an article on Bartok's sixth string quartet, composed in 1939 as he was planning to leave Hungary. quoted in the article, a 1938 letter Bartok wrote to Sacher after die Deutsche marched over Austria and absorbed it into their reich. "There is the imminent danger that Hungary will also surrender to this system of robbery and murder." he goes on to describe living and working under German occupation would be 'inconceivable'. also in this article, his response when his Vienna publisher, Universal editions, after its 'reformation' under the fascisti, sent him and Kodaly forms requesting verification of their 'Aryan pedigree'.
the town of Bartok's birth was part of the Austro Hungarian empire at the time, and with the numerous political shifts since, it is actually part of Roumania at present, and the town of his childhood is now located in the borders of Slovakia. one of his early piano instructors was a student of Liszt, and with his academic degrees from Budapest, Bartok was probably very capable (possibly required to in the conservatory) of performing Liszt quite well, something we'd hardly associate him with now.
his third piano concerto was composed in the last years of his life when he lived in the u.s., for his second wife, mother of Peter, the editor of the modern editions of some of his father's compositions. it was published posthumously, and Lipatti's performance might have been just its second performance after Bartok's widow. Bartok not only shared Lipatti's homeland, but medical affliction as well, leukaemia. peace
