A key catalyst of the late-'60s British blues boom, this 1966 milestone brought Mayall attention and Clapton to the brink of stardom. This might be the best British blues album ever, with All Your Love; Parchman Farm; Hideaway; Rambling on My Mind (featuring Clapton's first recorded vocals!) and more. Bonus tracks: both sides of their rare Lonely Years/Bernard Jenkins single, recorded prior to the LP!
