When I was in university in the, ahem, 70's, I got involved with a bunch of guys totally into music. I was too, but no where near the level these guys were. One album above all changed things for me forever. And if you know your music history, you will know that much of the British Blues came from John Mayall and his Bluesbreakers. Mick Fleetwood, John McVie, Peter Green, Mick Taylor, Clapton, Jeff Beck for a stint, the list goes on and on of seminal acts that came from his bands.
Anyway, this one double record changed how I viewed music forever.
