In June 1970, hot off their spectacular Grammy® win for Album of the Year (besting The Beatles’ “Abbey Road”), 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. Like much of the youth in America, band members have been outspoken and critical of the Nixon administration and the Vietnam War. The Iron Curtain Tour seems to be a curious decision by the band, which was at the very height of their popularity. Upon their return, the band becomes a victim of the significant societal upheaval and culture wars in a polarized America, and Blood, Sweat & Tears find themselves in the crossfire from both the political Right AND Left. 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.
