Sheila Escobedo was already a distinguished percussionist when she met Prince in 1978. But this song, the closing track on her 1984 debut solo album, has become her signature jam—reaching No. 1 on the U.S. dance charts, No. 7 on the U.S. pop charts, and earning two Grammy nominations. Although Sheila’s drum solo was not included on the song’s radio edit, her live performances of the tune are legendary.
