Peter Lichtenthal, born Wolfgang Mayer in 1779 in Bratislava, was not only a physician, but also a composer and author, including of two Mozart biographies, to which high authenticity can be attributed due to his acquaintance with Constanze Mozart and his two sons Carl and Franz. As a great admirer of the genius Mozart, he created numerous transcriptions of Mozart's works. On it's first CD of a two-part series by the title "Doktor Lichtenthals MOZART", which is now released, the Pandolfis Consort presents piano works by W. A. Mozart in arrangements by Lichtenthal. On period instruments, the Consort takes over the function of the entire orchestra as a string quartet in the Concerto for Piano and Orchestra No. 20 in D minor, K. 466, featuring the Romanian pianist Aurelia Visovan on the likewise historic fortepiano. The Fantasy for Piano No. 4 in C minor, K. 475, and the Piano Sonata No. 14 in C minor, K. 457, also included on the CD, were extended by Peter Lichtenthal with a cello part, which is interpreted by Günter Schagerl.
