Roots of Otis Rush

Riley B. King, known professionally as B. B. King, was an American blues guitarist, singer, songwriter, and record producer. He introduced a sophisticated style of soloing based on fluid string bending, shimmering vibrato, and staccato picking that influenced many later electric guitar blues players. AllMusic recognized King as "the single most important electric guitarist of the last half of the 20th century".

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.
