Answer by taking a quote from the following article:

Freddie King (September 3, 1934 - December 28, 1976) was an American blues guitarist and singer. He has been described as one of the "Three Kings" of electric blues guitar, along with Albert King and B.B. King. He was an influential guitarist with hits for Federal Records in the early 1960s. His soulful and powerful voice and distinctive guitar style inspired countless musicians, particularly guitarists (Eric Clapton is a notable example).

In 1959 King got to know Sonny Thompson, a pianist, producer, and A&R man for Cincinnati's King Records. King's owner, Syd Nathan, signed King to the subsidiary Federal Records in 1960. King recorded his debut single for the label on August 26, 1960: "Have You Ever Loved a Woman" backed with "You've Got to Love Her with a Feeling" (again credited as "Freddy" King). From the same recording session at the King Studios in Cincinnati, Ohio, King cut the instrumental "Hide Away," which the next year reached number 5 on the R&B chart and number 29 on the Pop chart, an unprecedented accomplishment for a blues instrumental at a time when the genre was still largely unknown to white audiences. It was originally released as the B-side of "I Love the Woman". "Hide Away" was King's melange of a theme by Hound Dog Taylor and parts by others, such as "The Walk", by Jimmy McCracklin, and "Peter Gunn", as credited by King. The title of the tune refers to Mel's Hide Away Lounge, a popular blues club on the West Side of Chicago. Willie Dixon later claimed that he had recorded King performing "Hide Away" for Cobra Records in the late 1950s, but such a version has never surfaced. "Hide Away" became a blues standard. After their success with "Hide Away," King and Thompson recorded thirty instrumentals, including "The Stumble," "Just Pickin'," "Sen-Sa-Shun," "Side Tracked," "San-Ho-Zay," "High Rise," and "The Sad Nite Owl". They recorded vocal tracks throughout this period but often released the tunes as instrumentals on albums. During the Federal period, King toured with many notable R&B artists of the day, including Sam Cooke, Jackie Wilson, and James Brown.
