In June 1970, hot off their spectacular Grammy® win for Album of the Year, Blood, Sweat & Tears becomes the first American rock band to perform behind the Iron Curtain, doing concerts in Yugoslavia, Romania and Poland on a tour sponsored by the U.S. State Department. Upon their return, the band becomes a victim of the significant societal upheaval and culture wars in a polarized America. Political criticism typically comes from one side or the other. But in 1970, Blood, Sweat & Tears find themselves in the crossfire from both the Right AND the Left and the group suffers greatly as a result. Suddenly, they are no longer hip and cool and lose support from fans, the media, concert bookers and the recording industry. Through documentary footage shot during the Iron Curtain tour (and thought to be lost) and present-day interviews with band members and historians, as well as the unsealing of government records, WHAT THE HELL HAPPENED TO BLOOD, SWEAT & TEARS? unravels the details of this extraordinary year in the life of the band.
