By January 5, 1967, the Jimi Hendrix Experience's first single, "Hey Joe", backed with "Stone Free", 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.
