Marz is the eleventh track on Prince's 36th album Plectrumelectrum (the first by Prince and 3rdEyeGirl).
It is assumed that a studio version was recorded in 2013 or early 2014 at Paisley Park Studios in Chanhassen, Minnesota. The track was premiered live on 9 February 2014, O2 Shepherd's Bush Empire, London, England (after appearing on a written setlist at a show three days earlier, along with Wow).
The track's opening line, "I lost my job at Mickey D's, gave away too much food for free", was also used in the (seemingly-improvised) track Midnight Blues, streamed in June 2013. Since that track is largely instrumental, it is possible that Marz was already recorded, and that Prince used the opening lines of the track while jamming on Midnight Blues, although since the lyrics beyond that opening line are different, it could simply be that Prince liked the lyric and decided to reuse it (while Midnight Blues was streamed live once but not mentioned nor performed again).
