I recently watched 'The Third Man' and thought that was one hell of a soundtrack!!(And the movie too!!)
It was composed by Anton Karas who played the Zither, who was a wine bar performer in Vienna. The director heard Anton play in a cafe and knew he found his composer for the film. Anton agreed to record some of his own compositions on a reel-to-reel tape machine that the director set up in the bedroom of his hotel in vienna. One of these was later to become the Harry Lime Theme and become a popular hit. Anton worked up to 14 hours a day for twelve weeks straight to make this score. The exposure made Karas an international star after the movie was released, he toured the world and played for royalty.....The success of the score also caused a surge in zither sales
Before Stevie Nicks there was Peter Green, he originally formed the band in 1967. He took too many drugs (LSD), toured Europe and joined a commune and quit the band in 1970. B.B King said, "He has the sweetest tone I ever heard; he was the only one who gave me the cold sweats".
