The American tenor saxophone player Buck Hill (1927). He was always underestimated because he was a mailman in his birthplace Washington D.C. for 30 years. At the end of the seventies he went public more often with his energetic and swinging performance. Recordings of his first CD from 1978 and live recordings during the North Sea Festival in 1981.
