Little Walter could make his harp sound like a tenor sax; he was instrumental in defining the sound that is now known as Chicago blues harp. Singer, composer, bandleader and peerless harmonica virtuoso, Little Walters music in virtually all its significant details was forged in the crucible of the emerging and maturing postwar Chicago Blues. It was as a member of, and a vital contributor to the Muddy Waters band that Walter was given full rein to stretch his wings, and it is a tribute to Muddy's foresight and generosity of spirit that he early recognized Walter's great talent and allowed him every opportunity and encouragement to develop it.
Little Walter, born Walter Marion Jacobs on May 1, 1930 in Marksville, Louisiana, taught himself harmonica age at the age of 8. He ran away from home, formed a group and worked the streets and small clubs of New Orleans in 1942. He worked in the Helena, Arkansas area from 1943-1946, performing on 'King Biscuit Time' and with Houston Stackhouse. When he was fourteen he came under the influence of Rice Miller, who along with Walter Horton, gave him pointers on the harp. The following year, Little Walter’s evolution beyond traditional folk-blues began when he started to listen to the records of jump saxophonist Louis Jordan and learn his solos note for note on harmonica.
Jacobs moved to Chicago around 1946 and played on Maxwell Street and in clubs with Tampa Red, Bill Broonzy, and Memphis Slim. His first recordings in 1947 were for Ora Nelle, a small Maxwell Street record label. After Muddy Waters started recording for Chess in 1947 with Ernest Big Crawford on bass. In 1948 he added Walter on harmonica, Jimmy Rodgers on second guitar, and Leroy Foster on drums to his band, and this group of musicians defined the modern blues band through their experience playing in Chicago's clubs. Their first recordings appeared on Chess in 1950, all classics of postwar blues. Walter's innovative playing and distinctive sound from his amplified harmonica contributed heavily to making Muddy's recordings of the early 1950's the magnificent achievements they still are. Walter toured with the Muddy Water's band during the years 1948-1952.
