This strong psychedelic trip record clearly shows how great Peter Green was at the time. The End of the Game is a hallucinatory mix of jazz, fusion, and blues. The edited pieces of a long jam session are experimental and all instrumentals. Peter Green's wah-wah Gibson guitar is incredibly expressive as is his band. It's a journey that Fleetwood Mac didn't want to make, but Green did it in a mind-blowing way.

In 1967 Peter Green, Mick Fleetwood, and John McVie played in the legendary John Mayall & The Blues Breakers and were given free studio time during which they recorded five songs. Peter Green was so convinced of this band´s musical prowess that he formed Fleetwood Mac on the spot and named it after the drummer & the bass player.
