Harmonica Fats (born Harvey Blackston, September 8, 1927 – January 3, 2000) was an American bluesharmonica player who was active in the 1950s through to the 1990s. Fats first achieved success with his cover version of the Hank Ballard song “Tore Up” in 1962, which established him as an in-demand sessionand touring musician. He is also remembered for his collaboration with blues guitarist Bernie Pearl, a partnership that resulted in four albums.

Born in McDade, Louisiana, a small community 40 miles from Shreveport, Blackston, the eldest of 13 children, was raised on a cotton farm by his grandparents. Blackston casually played harmonica since he was four years-old, and credited Sonny Terry as the foremost influence on his style of playing. Bored with the farming lifestyle, in 1946 Blackston relocated to Los Angeles where he lived with his father, and worked for a manufacturing company.
