Birdland by weather report
"Birdland" is a jazz/pop piece written by Joe Zawinul of the band Weather Report as a tribute to the Birdland nightclub in New York City, which appeared on the band's 1977 album Heavy Weather. The Manhattan Transfer won a Grammy Award with their 1979 version of the song, which had lyrics by Jon Hendricks. Quincy Jones won two Grammy Awards for the version of the piece he included on his 1989 album Back on the Block. The leading Cuban band Los Van Van included an extended interpolation of the piece in their song Tin Pop.
Great fusion music. So many fusion bands just don't pull it off. These guys did it to perfection
