The Mystery Of Love By Mr Fingers (1985)
The Mysteries Of Love was a landmark release in multiple ways. It was Larry Heard's first release. It was the first release on his own label. It's one of the first three tracks that he made when he first bought his synthesizers. It's arguably the origin of Deep House.
The original mix was an instrumental. The track was later re-recorded with Robert Owens doing an amazing vocal. I couldn't find the original release online, but the instrumental version that was later released on DJ International was the same version, but slightly shortened by the fade out at the end.
