Riley B. King (born September 16, 1925), known by the stage name B.B. King, is an American songwriter, vocalist, and famed blues guitarist.

Rolling Stone magazine ranked him at No. 6 on its list of the 100 greatest guitarists of all time. and No. 17 in in Gibson's Top 50 Guitarists of All Time. According to Edward M. Komara, King "introduced a sophisticated style of soloing based on fluid string bending and shimmering vibrato that would influence virtually every electric blues guitarist that followed." King was inducted into the Rock and Roll Hall of Fame in 1987.

King was born in a small cabin on a cotton plantation outside of Berclair, Mississippi, to Albert King and Nora Ella Farr on September 16, 1925.

Eric Patrick Clapton, CBE, (born 30 March 1945) is an English guitarist and singer-songwriter. Clapton is the only three-time inductee to the Rock and Roll Hall of Fame: once as a solo artist, and separately as a member of The Yardbirds and Cream. Clapton has been referred to as one of the most important and influential guitarists of all time. Clapton ranked second in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time" and fourth in Gibson's Top 50 Guitarists of All Time.

In the mid 1960s, Clapton departed from the Yardbirds to play blues with John Mayall & the Bluesbreakers. In his one-year stay with Mayall, Clapton gained the nickname "Slowhand". Immediately after leaving Mayall, Clapton formed Cream, a power trio with drummer Ginger Baker and bassist Jack Bruce in which Clapton played sustained blues improvisations and "arty, blues-based psychedelic pop." For most of the 1970s, Clapton's output bore the influence of the mellow style of J.J. Cale and the reggae of Bob Marley. His version of Marley's "I Shot the Sheriff" helped reggae reach a mass market. Two of his most popular recordings were "Layla", recorded by Derek and the Dominos, another band he formed and Robert Johnson's "Crossroads", recorded by Cream. A recipient of seventeen Grammy Awards, in 2004 Clapton was awarded a CBE for services to music. In 1998, Clapton, a recovering alcoholic and drug addict, founded the Crossroads Centre on Antigua, a medical facility for recovering substance abusers.

George "Buddy" Guy (born July 30, 1936) is an American blues guitarist and singer. Critically acclaimed, he is a pioneer of the Chicago blues sound and has served as an influence to some of the most notable musicians of his generation. "A key influence on Eric Clapton, Jimi Hendrix and Stevie Ray Vaughan, Buddy Guy put the Louisiana hurricane in 1960s electric Chicago blues as a member of Muddy Waters' band and as a house guitarist at Chess Records. A native of the Baton Rouge area, he combined a blazing modernism with a fierce grip on his roots, playing frantic leads heavy with swampy funk on Howlin' Wolf's 'Killing Floor' and Koko Taylor's 'Wang Dang Doodle' as well as on his own Chess sides and the fine series of records he made with harp man Junior Wells. One of the last active connections to the golden age of Chess, Guy still plays with his original fire."

Ranked thirtieth in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time", Guy is known for his showmanship on stage: playing his guitar with drumsticks or strolling into the audience while playing solos. His song "Stone Crazy" was ranked seventy-eighth in list of the 100 Greatest Guitar Songs of All Time also of Rolling Stone.
