By January 5, 1967, the Jimi Hendrix Experience's first single, "
Hey Joe", backed with "
Stone Free", had peaked at number six on the UK record chart. "Hey Joe" was not a Hendrix composition – it was written by
Billy Roberts and recorded by several groups prior to the Experience. Hendrix commented, "That record isn't us. The next one's gonna be different. We're working on an LP which will mainly be our stuff." The group recorded several demos of original material at studios in London, including "Can You See Me", "
Foxy Lady", "
Third Stone from the Sun", "
Red House", and "Remember". In the middle of December, producer
Chas Chandler heard Hendrix toying around with a new guitar riff. "I heard him playing it at the flat and was knocked out. I told him to keep working on that, saying, 'That's the next single! Chandler claimed that after some more urging, Hendrix wrote the rest of "Purple Haze" in the dressing room of a London club during the afternoon of December 26, 1966, before a gig. In several interviews, Hendrix spoke about writing the song, but did not mention where or when he wrote it. The Experience began recording "Purple Haze" on January 11, 1967, at
De Lane Lea Studios in London. According to drummer
Mitch Mitchell, he and bassist
Noel Redding learned the song in the studio: "Hendrix came in and kind of hummed us the riff and showed Noel the chords and the changes. I listened to it and we went, 'OK, let's do it.' We got it on the third take as I recall." The basic track was recorded in four hours, according to Chandler.
Multitrack recording technology allowed engineers to record and complete additional parts on the final master. After the basic track was finished, Chandler explained that he and Hendrix developed the song: Redding and Mitchell were not included in the process because Chandler felt that it was more efficient for him and Hendrix to do it alone. To get a better quality recording, Chandler took the four-track tape recorded at De Lane Lea to
Olympic Studios for
overdubbing (although Hendrix had worked with eight-track recording in the US, it was not yet available in the UK). At Olympic, they were assigned
Eddie Kramer, who, as a sound engineer, played an important role in subsequent Hendrix recordings. Hendrix added new vocals and guitar parts between February 3 and 8, 1967. Unlike the conventional techniques used by the Experience to record previous songs, Chandler decided to try out new effects and sounds for "Purple Haze". He enhanced background sounds (some contributed by Redding) by playing them back through headphones, which were moved around the recording microphone, creating "a weird echo". Chandler also used sped-up guitar parts recorded at half-speed (which also raises the
pitch) and
panning to create novel effects. The guitar solo features the first use of the
Octavia guitar effects unit. Acoustical and electronics engineer
Roger Mayer developed the unit with input from Hendrix. The Octavia doubles the frequency of the sound it is fed, essentially adding an upper octave. ==Lyrics and interpretation==
