John Mayall brought to the world the Eric Clapton we know today. Their 1966 album <i>"Blues Breakers With Eric Clapton"</i> changed everything in rock music. That is when the highly cranked Marshall guitar amplifier and the Gibson Les Paul (brought out of retirement) came to life and became the icons they're known for today.<p>RIP John Mayall. You, your protégés, their protégés, and those they've all influenced, have brought us a lot of great music!
