2010 four CD anthology from the British Blues legend. John Mayall's band, The Bluesbreakers ,were undoubtedly a hot-house for the British Blues scene in the late '60s and early '70s and it's quite staggering when you examine the roll call of floating members who served their apprenticeship with John Mayall including Jack Bruce, Eric Clapton, Mick Fleetwood, Peter Green, Keef Hartley, John McVie, Mick Taylor and Steve Winwood.  This lavish box set contains 74 tracks, all newly remastered from the original master tapes, including five tracks released in Europe on CD for the first time. The 40-page booklet features sleevenotes by Mark Powell with rare and previously unseen photographs. Universal.
