AC/DC vocalist Bon Scott fronted AC/DC from 1974 up until his death in 1980. Before he was rocking out loud, Scott fronted a much proggier band named Fraternity starting in 1970. The band's material has been largely unavailable for the past few decades, but is finally seeing an official release as a 3CD set titled Seasons of Change.
The box features both Fraternity albums Livestock and Flaming Galah, as well as a collection of rarities and a lost third album called Second Chance. The band is basically the opposite of what AC/DC sounded like, as you can hear below. There are also a lot of recorded used throughout this song played by Scott, mainly because it's progressive rock in the 1970s.
