Johann (Hans) Hölzel (19 February 1957 – 6 February 1998), better known by his stage name Falco, was an Austrian pop and rock musician and rapper. He had several international hits: "Rock Me Amadeus", "Der Kommissar", "Vienna Calling", "Jeanny", "The Sound of Musik", "Coming Home (Jeanny Part 2)" and posthumously, "Out of the Dark". "Rock Me Amadeus" reached No. 1 on the Billboard charts, making him the only artist whose principal language was German to score a number-one hit in the United States. His estate claims he has sold 20 million albums and 15 million singles, which makes him the best selling Austrian singer of all time.
