Little Walter (Marion Walter Jacobs) came to Chicago in 1945 and by 1948 was playing harmonica for Muddy Waters. He left Muddy’s band in 1952 and started fronting his own band. His first single, “Juke,” reached #1 on the Billboard R&B chart, and he was to have 14 Top 10 hits for Checker Records (a subsidiary of Chess Records) over the next 15 years. He pioneered the use of the amplified harmonica, using a small handheld microphone, and experimented with various effects including reverb and distortion. “Shake Dancer” was one of his later singles, recorded in 1964, though it didn’t chart.
