Whenever I explain why I’m writing about every Prince song in order–a hobby, believe it or not, that does still warrant explanation in some circles–one of my go-to lines is that Prince, almost uniquely in popular music, is an artist with effectively three or four different canons. There is of course the primary canon of the big ’80s hits (“1999,” “Kiss,” “Little Red Corvette,” basically all of Purple Rain), f0llowed by the subcanon of later singles, “deep cut” album tracks, and B-sides–the latter of which is large enough that we could potentially make it a subcanon all its own. But what makes Prince special is the fact that he also has a sub-subcanon–either his third or fourth, depending on how we count the above–which includes tracks that never saw official release, but are still treated with reverence by collectors and fans. Prince isn’t the only artist with a deep and multilayered catalogue, of course–Bob Dylan and Neil Young both come to mind as potential peers–but I would argue that he is the only artist whose “sub-subcanon” rivals the quality and notoriety of his “official” body of work. In short, for fans of rabbit holes (and I clearly am one), they don’t come any deeper than this.
For years, “Cosmic Day” was one of those fabled cuts languishing in the depths of the purple rabbit hole: one of many proverbial “holy grails.” Recorded on November 15, 1986, in the midst of the blur of activity that led to the Crystal Ball triple-LP and its truncated sibling, Sign “O” the Times, it was seemingly never intended for either project; like “Moonbeam Levels,” another fixture of Prince’s subterranean canon, it’s at once essential to the era in which it was recorded and wholly detached from it. But unlike “Moonbeam Levels,” it has also tantalized fans by staying out of the hands of most collectors, with only two-to-three-minute fragments in wide circulation–until, that is, yesterday’s release of the full recording in advance of Sign “O” the Times Super Deluxe.
