Samuel Gene Maghett, known as Magic Sam, was an American Chicago blues musician. He was born in Grenada County, Mississippi, and learned to play the blues from listening to records by Muddy Waters and Little Walter. After moving to Chicago at the age of 19, he was signed by Cobra Records and became well known as a bluesman after the release of his first record, "All Your Love", in 1957. He was known for his distinctive tremolo guitar playing.

Cobra Records was an independent record label that operated in Chicago from 1956 to 1959 and launched the careers of Chicago blues artists Otis Rush, Magic Sam and Buddy Guy, a new generation who pioneered the West Side Sound.
