Heinrich Isaac: Innsbruck, Ich muss dich lassen

Heinrich (Hendrick) Isaac (around 1450-55 March 26, 1517) was a Franco-Flemish composer of the Renaissance born in Flanders, likely in Brabant. He is regarded as one of the most significant contemporaries of Josquin des Prez, and had an especially large influence on the subsequent development of music in Germany.
