Leroy Vinnegar

Leroy Vinnegar (July 13, 1928 – August 3, 1999) was an American jazz bassist. Born in Indianapolis, Indiana, United States, the self-taught Vinnegar established his reputation in Los Angeles, California, during the 1950s and 1960s. His trademark was the rhythmic "walking" bass line, a steady series of ascending or descending notes, and it brought him the nickname "The Walker". Besides his jazz work, he also appeared on a number of soundtracks and pop albums, notably Van Morrison's 1972 album, Saint Dominic's Preview.
