With the original plan of a live album now discarded, John Mayall & the Bluesbreakers recorded Blues Breakers at Decca Studios, West Hampstead, London in May 1966.

[5] The guitar that Eric Clapton used during these sessions was a sunburst 1960 Gibson Les Paul Standard with two PAF humbucking pickups.

[8] The band on this album includes Mayall on piano, Hammond organ, harmonica, and most vocals; bassist John McVie; drummer Hughie Flint; and Clapton.

[9] Augmenting the band on this album was a horn section added during post-production, with Alan Skidmore, Johnny Almond, and Derek Healey.

[9] The album consists of blues standards by well-known artists, such as Otis Rush, Freddie King and Robert Johnson, as well as a few originals penned by Mayall and Clapton.

[21] Apart from being one of the most influential blues albums, it also started the now-iconic combination of a Gibson Les Paul guitar through a overdriven Marshall Bluesbreaker amplifier.
