Although Fleetwood Mac is best known for the mellow rock of RUMORS and TUSK, the quintessential '70s L.A. band started out as a British blues-rock powerhouse led by guitar genius Peter Green. After a stint in John Mayall's Bluesbreakers, Green formed Fleetwood Mac with the sidemen of the title, Mick Fleetwood and John McVie. After a mere three albums of quintessential Brit blues, Green left to explore the darker regions of LSD culture. Though he returned to music in the '70s, and continued to record and tour sporadically into the '90s, it's been said by many that Green never really came back from those trips. Nonetheless, Peter Green is known to this day for having perhaps the most sweet and supple tone of any blues guitarist, British or otherwise.
