In 1970, Blood, Sweat and Tears was one of the biggest bands in the world. They had exploded on the scene with both daring and promise, selling millions of records, winning multiple Grammy Awards including Album of the Year (beating out The Beatles Abbey Road) and headlining the legendary Woodstock festival. In demand for concert and TV appearances, BS&T was a darling of the mainstream and rock press, icon of the counterculture and inspiration for a generation of horn-based bands. Their future was limitless. And then it all went wrong.
