Mars could refer to one of many acts. Organized chronologically by order of inception, they include:

1) New York-based "No Wave" act formed in 1975, best known for their contribution to the seminal Brian Eno-produced compilation, No New York. Originally called "China", the band that would become Mars would play only a handful of shows in their short career and would be limited to a handful of recorded tracks. The band was headed for split up in 1978 — regardless of their appearance on No New York — but managed to stay together long enough to record material for an EP, a self-titled affair, posthumously released in 1980. This EP, along with an early 7" and live tracks, was released as a compilation — titled 78+ — in on the Widowspeak label in 1986. Atavistic would re-release the compilation in 1996, and Mars bassist Mark Cunningham's label Spooky Sound would release The Complete Studio Recordings in 2003. Founders Sumner Crane and Nancy Arlen, who started the band with Cunningham, Constance "China" Burg, and Rudolph Grey in 1975, tragically passed away in 2003, and 2006, respectively.

2) The alias used by Mario Delgado, a Bay-era rapper. Celebrated by supporters who dub themselves "Mad Insanes" as a crusader for Horrorcore music, a genre of rap music in its most extreme form who's subjects include but not limited to Murder, Rape, Abortion, Drugs, and Satanism.
