Blood, Sweat & Tears was an American music group, formed in New York City in 1967, which fused jazz and rock or pop music into a hybrid of what came to be known as "jazz-rock". They are among the first of this genre of music. Unlike "jazz fusion" or simply "fusion" (which tended toward virtuostic displays of electronic experimentation and amodal music), Blood, Sweat & Tears' sound was a merging of the varied stylings of rock, pop and R&B/soul music with big band or combo jazz.
