Samuel "Magic Sam" Gene Maghett (February 14, 1937 – December 1, 1969) was an American Chicago blues musician. Maghett was born in Grenada, 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 nineteen, he was signed by Cobra Records and became well known as a bluesman after his first record, "All Your Love" in 1957. He was known for his distinctive tremolo-guitar playing.
After moving to Chicago in 1950, his guitar playing earned bookings at blues clubs on Chicago's West Side. Sam recorded for Cobra Records from 1957 to 1959, recording singles including "All Your Love" and "Easy Baby". They did not appear on the record charts, yet they had a profound influence, far beyond Chicago's guitarists and singers.
