This unreleased live recording is a small moment in history. It is the second volume of the "Live In 1967" series, featuring an exceptional lineup of musicians. It is thanks to a fan of the Bluesbreakers, Tom Huissen, who carried his portable tape recorder from club to club in 1967. Remaining unreleased for almost fifty years, these tapes came into the possession of John Mayall and underwent careful restoration. Even though the sound source was dusty and certainly not up to current stereo standards, this album allows us to immerse ourselves in the London night at the heart of a feverish and spectacular "power blues" performance.
