Burns 1 is an unreleased track by poet/rapper Ninety-9, recorded in 1993, at Paisley Park Studios in Chanhassen, Minnesota (during the same set of sessions as 40 Ounces, The Mood For Love, Stained Glass and Three Shots). The track is thought to be co-written and produced by Prince (as ). Although Prince and Ninety-9 have worked together on a series of songs it is unclear whether this short-lived collaboration was intended to lead to an album or to a particular project. Prince sampled the tracks heavily in 1993-5 recordings, however. A significant portion of the rap, as well as a looped sample of "Sex me?", was used in Joint 2 Joint.
A lyrically identical but musically different version of the song without any Prince involvement was released on the album Subliminal Simulation by the band Dream Warriors in 1994 (Canada) and 1995 (USA). Since that version lacks any Prince involvement the track (as Burns 1) is still regarded unreleased.
