Earl Zebedee Hooker was a Chicago blues guitarist known for his slide guitar playing. Considered a "musician's musician", he performed with blues artists such as Sonny Boy Williamson II, Junior Wells, and John Lee Hooker and fronted his own bands. An early player of the electric guitar, Hooker was influenced by the modern urban styles of T-Bone Walker and Robert Nighthawk. He recorded several singles and albums as a bandleader and with other well-known artists. His "Blue Guitar", a slide guitar instrumental single, was popular in the Chicago area and was later overdubbed with vocals by Muddy Waters as "You Shook Me".

John Lee Curtis "Sonny Boy" Williamson was an American blues harmonica player and singer-songwriter. He is often regarded as the pioneer of the blues harp as a solo instrument. He played on hundreds of recordings by many pre–World War II blues artists. Under his own name, he was one of the most recorded blues musicians of the 1930s and 1940s and is closely associated with Chicago producer Lester Melrose and Bluebird Records. His popular songs, original or adapted, include "Good Morning, School Girl", "Sugar Mama", "Early in the Morning", and "Stop Breaking Down".

Robert Lee McCollum was an American blues musician who played and recorded under the pseudonyms Robert Lee McCoy and Robert Nighthawk. He was the father of the blues musician Sam Carr. Nighthawk was inducted into the Blues Hall of Fame in 1983.
