Frank Otis Frost (April 15, 1936 or 1938 – October 12, 1999)[1] was one of the foremost American Delta blues harmonica players of his generation.

[1] Frost began his musical career at a young age by playing the piano for his family church.

Some recordings of note that followed included "Hey Boss Man" and "My Back Scratcher".

[6] In the late 1970s, Frost was re-discovered by a blues enthusiast, Michael Frank, who began releasing albums on his Earwig Music Company label by the trio, now called The Jelly Roll Kings, after a song from their album, Hey Boss Man.

Four days before his death, he appeared with Carr at the King Biscuit Blues Festival.
