Tracks 4 7, 10, 12 and 16 from Sheila E. (1987)

Tracks 8, 13 and 18 from Sex Cymbal (1991)

There's a (somewhat accurate) stereotype that most 'Prince proteges' were beautiful women of negligible musical talent who he could shape into whatever image he wanted and perform whatever material he gave them. Sheila E. was different, though, a seasoned drummer who was a little older than Prince, came from a famous musical family (her father's percussionist Pete Escovedo and her uncle's singer/songwriter Alejandro Escovedo) and had played with legends like Marvin Gaye and Herbie Hancock in the '70s when she first met Prince while he was getting his career off the ground. 

Of course, by the time Sheila E. really became part of the Prince crew, he was a superstar with a stable of acts recording his songs. Sheila E. played and/or sang on classics including "Erotic City," "Pop Life," "Alphabet Street," "Strange Relationship," and "Girls & Boys," and her early Prince-produced 

albums paralleled his peak period. The Glamorous Life was released a few weeks before Purple Rain, Romance 1600 was released a few months after Around The World In A Day, and Sheila E. was released a few weeks before Sign O' The Times. And I really love her voice on some of these tracks, she's a little more expressive as a singer than the Vanity/Apollonia types that often sang Prince's songs. 

The 2019 posthumous Prince album Originals, which collected his original solo demos for songs released by other artists, had four Sheila E. songs on it, a couple of singles as well as "Dear Michaelangelo" and "Noon Rendezvous." Sheila E. has released 8 solo albums, but a couple of them, 2000's Writes Of Passage and 2001's Heaven, aren't available on streaming services. Sex Cymbal is a pretty funny album title, but I suppose Sheila E. may as well have used that pun since there are barely any other famous drummers who can be accurately described as a sex symbol (maybe, I dunno, Larry Mullen Jr., but he's never made a solo album).
