This 1967 photo provided by the Stax Museum of American Soul Music shows Stax Records musicians at an airport during their tour of Europe. From left are Eddie Floyd, Sam Moore, Steve Cropper, Otis Redding, Wayne Jackson and Arthur Conley. Artists from the studio captivated audiences with their music born from blues and gospel — a mesmerizing sound created from the black experience in the U.S. last century.
