The band's early sound was jazzy, but evolved into an exuberant, horn-driven mix of jazz, funk, gospel and big band. That band found success onstage, its concerts a mix of dancing, fog machines, multi-colored lights and glittery costumes. Earth, Wind & Fire performed at the Super Bowl and the White House.
