Bowie’s exit — the release of his album only days before his death, the video of “Lazarus,” the timing of it all — is in no way an accident, and was absolutely planned. His producer confirms it.
A commenter on Metafilter calls it a “nothing-but-net exit,” which to me just about sums it up.
You should never doubt that he was, in addition to so much else, an unstoppable conceptual bastard.
