and minor modes, it is described as "haunting" by Power and as a "distinctive piercing, sinister tone" by critic Richie Unterberger. In the second section, the piano, bass, and drums come in and the tension builds. Unterberger describes the third section as "suddenly set[ting] off from the main motif into a beautiful serene section highlighting slide-glissando guitars", with Beck's echo-laden slide sounding similar to a steel guitar. The fourth section returns to the main melody with overlaid drawn-out descending slide. According to Beck, "the phasing was Jimmy's idea ... I played a load of waffle and he reversed it". The tension mounts as Moon adds drum flourishes, climaxing with a break. The second part begins with Moon's simultaneous drum break and scream and launches in different, hard rock direction. "It was my idea to cut off in the middle, Yardbirds-style", Beck commented, "Keith upped the tempo and gave it an extra kick. It's like a bit of the Who, a bit of the Yardbirds and a bit of me". The amply-distorted guitar provides "a thick-toned, descending riff", according to Power. He also describes the break, inspired by the Yardbirds' rave-up technique, as "eerily presag[ing] the coming era of hard rock and heavy metal". The third part returns to the main motif with added guitar fills. The melody line is abandoned in the second section and replaced with multiple interwoven takes of guitar effects, including phasing, echo, and controlled feedback. It concludes with a few bars of hard blues rock-style lead guitar and an abrupt ending. Releases The record release of "Beck's Bolero" was delayed for ten months, when Jeff Beck began his solo career after leaving the Yardbirds. It appeared as the B-side of his first single, "Hi Ho Silver Lining", which was released on 10 March 1967 in the UK (Columbia DB 8151) and 3 April 1967 in the US (Epic 5–10157). The initial UK pressing of the single listed the title as "Bolero" with Jeff Beck as the composer, while later pressings showed "Beck's Bolero" and "J. Page". The single reached number fourteen in the UK Singles Chart, and number 123 in the US Billboard's Bubbling Under Hot 100 Singles chart. "Hi Ho Silver Lining" was ignored by American underground FM radio, but "Beck's Bolero" became a staple of the new radio format. In 1968, the instrumental gained wider exposure when it was included on the Jeff Beck
