"In Search of the Lost Chord" is the third studio album by the Moody Blues, released in July 1968 on the Deram label. The album explores themes of spirituality and consciousness, incorporating elements of rock, orchestral arrangements, and innovative sound techniques. It is notable for tracks like "Peak Hour" and "Ride My See-Saw," reflecting the band's evolving style during this period.
The success of the Moody Blues' previous album, Days of Future Passed, provided the band with more studio time and creative freedom for their follow-up, In Search of the Lost Chord. Keyboardist Mike Pinder expressed in the Melody Maker that albums allow for experimentation and offer listeners a chance to engage deeply with the music, rather than just dancing to it. Guitarist Justin Hayward reflected that this album marked a pivotal moment for the band, stating it was when they found their "soul and direction," as everything musically came together.
