Wolfgang Amadeus Mozart wrote his horn concertos for Joseph Leitgeb (1732-1811), a good friend of the family who was often the target of Mozart's crude humor. They were written during his time as a freelance composer in Vienna and today form an essential part of the concert repertoire for horn. Here they are interpreted by Sibylle Mahni, Professor of Horn at the Hanns Eisler School of Music Berlin, and the Brandenburg Symphony Orchestra under the direction of Andreas Spering in a rousing, emotional and, above all, "historically informed" performance.
