Blues rock is a musical genre combining bluesy improvisations over the twelve-bar blues and extended boogie jams with rock and roll styles. The core of the blues rock sound is created by the electric guitar, piano, bass guitar and drum kit, with the electric guitar usually amplified through a tube guitar amplifier, giving it an overdriven character.

The style began to develop in the mid-1960s in Britain and the United States. UK Bands, such as The Rolling Stones and The Animals and American bands such as the Butterfield Blues Band and the Siegel–Schwall Band, experimented with music from the older American bluesmen, like Albert King, Howlin' Wolf, Robert Johnson, Jimmy Reed, Muddy Waters, and B.B. King. While the early blues rock bands "attempted to play long, involved improvisations which were commonplace on jazz records", by the 1970s, blues rock got heavier and more riff-based. By the "early '70s, the lines between blues rock and hard rock were barely visible", as bands began recording rock-style albums. In the 1980s and 1990s, blues rock acts returned to their bluesy roots, and some of these, such as the Fabulous Thunderbirds and Stevie Ray Vaughan, flirted with rock stardom."

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.

James Douglas "Jim" Morrison (December 8, 1943 – July 3, 1971) was the lead singer and lyricist of the rock band The Doors, as well as a poet. Following The Doors' explosive rise to fame in 1967, Morrison developed a severe alcohol and drug dependency that culminated in his death at the age of 27 in Paris. He is presumed to have died from a heroin overdose, but as no autopsy was performed, the events surrounding his death and the exact cause of it continue to be disputed by many to this day.

Morrison was well known for often improvising spoken word poetry passages while the band played live. Due to his wild personality and performances, he is regarded by critics and fans as one of the most iconic, charismatic and pioneering frontmen in rock music history. Morrison was ranked number 47 on Rolling Stone's list of the "100 Greatest Singers of All Time", and number 22 on Classic Rock Magazine's "50 Greatest Singers In Rock".

James Douglas Morrison was born in Melbourne, Florida, to future Rear Admiral George Stephen Morrison and Clara Morrison. Morrison had a sister, Anne Robin, who was born in 1947 in Albuquerque, New Mexico; and a brother, Andrew Lee Morrison, who was born in 1948 in Los Altos, California. He was of Irish and Scottish descent.

John Lee Hooker (August 22, 1917 – June 21, 2001) was a highly influential American blues singer-songwriter and guitarist.

Hooker began his life as the son of a sharecropper, William Hooker, and rose to prominence performing his own unique style of what was originally a unique brand of country blues. He developed a 'talking blues' style that was his trademark. Though similar to the early Delta blues, his music was metrically free. John Lee Hooker could be said to embody his own unique genre of the blues, often incorporating the boogie-woogie piano style and a driving rhythm into his blues guitar playing and singing. His best known songs include "Boogie Chillen'" (1948), "I'm in the Mood" (1951) and "Boom Boom" (1962), the first two reaching R&B #1 in the Billboard charts.

There is some debate as to the year of Hooker's birth in Coahoma County, Mississippi, the youngest of the eleven children of William Hooker (1871–1923), a sharecropper and Baptist preacher, and Minnie Ramsey (born 1875, date of death unknown); according to his official website, he was born on August 22, 1917.
