Blood, Sweat & Tears

No late-'60s American group ever started with as much musical promise as Blood, Sweat & Tears, or realized their potential more fully -- and then blew it all in a series of internal conflicts and grotesque career moves. It could almost sound funny, talking about a group that sold close to six million records in three years and then squandered all of that momentum. Then again, considering that none of the founding members ever intended to work together, perhaps the group was "lucky" after a fashion.
