Little Walter (1930–1968) was an American blues artist who is generally regarded as the most influential blues harmonica player of his era. Most of his earliest recordings were as a sideman, when he contributed harmonica to songs by Chicago blues musicians such as Jimmy Rogers and Muddy Waters. As the featured artist, he recorded the instrumental "Juke" in 1952. The single reached number one on the Billboard Rhythm and Blues chart and launched his career as a solo artist.
