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 vocal number-one hit in the United States (Bert Kaempfert reached No. 1 in January 1961 with the instrumental "Wonderland by Night"). His estate claims he has sold 20 million albums and 15 million singles, which makes him the best selling Austrian singer of all time.
