Santana - Black Magic Woman

Release date: 1970
This was a hit for Santana, but few people know that this song is actually a cover of a 1968 Fleetwood Mac song. The original's music sounds very similar to the sound Santana added on his version.
A curious blend of blues, rock, jazz, 3/2 afro-Cuban son clave, and "Latin" polyrhythms, Santana's arrangement added conga, timbales and other percussion, in addition to organ and piano, to make complex polyrhythms that give the song a "voodoo" feel distinct from the original.
