Ethel Llewellyn Ennis is an American jazz musician.
Ethel Ennis began performing on the piano in high school, but her natural vocal abilities soon eclipsed those as a pianist. Embarking on a solo career, she recorded a number of sides for Atlantic Records before the Lp debut, 1955's Lullabies for Losers was released by Jubilee Records. In 1957, Ennis moved to the Capitol Records label for a two-album contract, and A Change of Scenery was released. Soon after the 1958 follow-up Lp Have You Forgotten, Ennis took a six-year hiatus from recording during which she toured Europe with Benny Goodman.
Ennis was again invited to the recording studios in 1963, recording four LPs for RCA Records. However, disenchanted with the creative direction of the label and artist management, Ennis left RCA and took another hiatus, this time eight years without a recording contract. During this period she sang the title song for the 1967 feature film Mad Monster Party. The BASF Lp 10 Sides of Ethel Ennis emerged in 1973 and later that year Ennis, a Democrat, was invited to sing at the re-inauguration of Richard Nixon. Ethel's unusual a cappella rendition of the national anthem shocked some, but inspired many others.
