Gundula Janowitz (soprano), Christa Ludwig (mezzo-soprano), Peter Schreier (tenor), Walter Berry (bass), Vienna State Opera Chorus, Vienna Symphony Orchestra, conductor: Karl Böhm. Recorded in Dezember 1971 in the Piarist Church, Vienna. The Requiem is not only Mozart's last composition, but also the one most shrouded in mystery. The purportedly enigmatic patron who ordered the work and the fatal illness that befell Mozart while he was working on it long nurtured the macabre legend of Mozart composing his own Requiem mass commissioned by Death himself. The Requiem was completed by Mozart's friend and pupil Franz Saver Süssmayr on the basis of Mozart's sketches and instructions.
