"Purple Haze" is a song written in 1966 by Jimi Hendrix and recorded in 1967, released as the second single by The Jimi Hendrix Experience in both the United Kingdom and the United States. It later appeared on the American version of the band's 1967 album Are You Experienced. "Purple Haze" has become one of the "archetypical psychedelic drug songs of the sixties". "Purple Haze" has been identified as possibly the first heavy metal hit and Hendrix's virtuosic techniques would be emulated by many metal guitarists.

Reportedly, the song came into being after the band's producer Chas Chandler heard him playing the riff backstage and suggested that he write lyrics to go with it. There is some dispute about the lyrics: supposedly written in the dressing room of the Upper Cut Club on Boxing Day, 1966, it is also believed that he wrote the lyrics in Westbourne Grove, Notting Hill. Chandler claims that the lyrics were never cut in any way (though he admits that this was done on general principle with Hendrix's lyrics), while Hendrix stated that the original song contained much more text. Hendrix himself denied the drug relation of the song claiming it to be merely another love song. He said that the line "What ever it is, that girl put a spell on me" is the key line to the lyrics.

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".

Robert William Gary Moore (4 April 1952 – 6 February 2011), was a Northern Irish musician, most widely recognised as a blues singer and guitarist.

In a career dating back to the 1960s, Moore played with artists including Phil Lynott and Brian Downey during his teens, leading him to memberships with the Irish bands Skid Row and Thin Lizzy on three separate occasions. Moore shared the stage with such blues and rock luminaries as B.B. King, Albert King, Colosseum II, George Harrison and Greg Lake, as well as having a successful solo career. He guested on a number of albums recorded by high profile musicians, including a cameo appearance playing the lead guitar solo on "She's My Baby" from Traveling Wilburys Vol. 3.

Moore started performing at a young age, having picked up a battered acoustic guitar at the age of eight. He got his first quality guitar at the age of 14, learning to play the right-handed instrument in the standard way despite being left-handed. He moved to Dublin in 1968 at the age of 16. His early musical influences were artists such as Albert King, Elvis Presley, The Shadows and The Beatles. Later, having seen Jimi Hendrix and John Mayall's Bluesbreakers in his home town of Belfast, his own style was developing into a blues-rock sound that would be the dominant form of his career in music.
