"In 1967, musicians Peter Green, Mick Fleetwood, and John McVie left their band the Bluesbreakers, and joined forces with Jeremy Spencer and Bob Brunning to form the original iteration of Fleetwood Mac. By the time their third album was released in 1970, the band was starting to achieve mainstream success, although several members were personally struggling. Green left the band first, after an alleged bad acid trip began to affect him mentally. He was replaced with Christine McVie, who is still a member of the band to this day. Following Green's departure, Spencer began to distance himself from the band, and even released a solo album."
