for additional overdubs, including Hendrix's lead vocal, backing vocals, and a percussion effect created by Chandler, Hendrix, and guests Graham Nash and Gary Leeds stamping their feet on a drum riser. As an additional oddity, Hendrix played a recorder on the track, achieving what they considered a satisfactory sound despite his complete lack of formal training with the instrument. Also recorded during these sessions was the experimental track "EXP". In the span of two days, the group recorded basic tracks for seven compositions, though only three were included on the album. On May 9, the Experience reconvened at Olympic with Chandler, Kramer and Chkiantz. Hendrix had been curious about a harpsichord that was stored in the facility's Studio A, so on this day he sat at the instrument and began writing "Burning of the Midnight Lamp", a song that became the fourth UK single for the Experience. Hendrix attempted four takes before stopping for the day, producing a rough demo that was approximately a minute and a half in length. On May 10, the band performed their latest single, "The Wind Cries Mary", on the BBC television program Top of the Pops. After a month-long break from the studio while playing gigs in Europe, the Experience returned to Olympic on June 5. They devoted the session to a new Hendrix song titled "Cat Talking to Me", recording 17 takes before deciding that the second was the superior version, to which they added guitar and percussion overdubs after Kramer prepared a reduction mix. It was later included on the posthumous album West Coast Seattle Boy: The Jimi Hendrix Anthology (2010). On June 18, 1967, the Experience made its U.S. debut at the Monterey Pop Festival. Immediately after the festival, Bill Graham booked them for a series of five concerts at the Fillmore. While they were in California, Chandler booked session time for June 28, 29 and 30 at Houston Studios in Los Angeles. Although they worked on "Burning of the Midnight Lamp" and a new Hendrix composition, "The Stars That Play with Laughing Sam's Dice", they abandoned the inferior recordings. Chandler commented: "I booked three days there because I was told it was a state-of-the-art studio, but it was dire. The place was like a rehearsal studio compared to Olympic. Los Angeles was so far behind at that time." After a week of performances in Los Angeles and New York, time
