Formed in 1968 by acclaimed drummer Aynsley Dunbar after his tenure with John Mayall’s Bluesbreakers and Jeff Beck, The Aynsley Dunbar Retaliation carved a distinctive place in late‑1960s British blues-rock. Blending raw blues intensity with exploratory musicianship, the group showcased Dunbar’s precise yet powerful drumming alongside original compositions that hinted at jazz and progressive influences. Their recordings, including four albums released between 1968 and 1970, earned critical respect and influenced contemporaries and future rock performers alike, cementing Dunbar’s reputation as one of Britain’s most versatile and dynamic drummers.
