Simlac (also known as Burns 1) is an unreleased track by poet/rapper Ninety-9 (real name : Dietra Moses) Prince (as ) worked on in late-Spring – early Summer 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). There might be other versions of the song with her own backing music as the five tracks known to have been worked or re-worked by Prince were registered on September 1st 1993 as musical compositions by Dietra Moses alone at the Library Of Congress.
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.
It is unclear whether this short-lived collaboration between Prince and Ninety-9 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 sample of "Diss me" from the track was used in studio and live versions of Days Of Wild and the phrase "He’s always on some medication" was included on Mad.
