Legend is an honorific that is all too often bandied about. In the case of David Bowie, it applies.
Bowie didn't just live a life without compromise, he lived many, his fictional personae more authentically lived than most contemporary celebrities' actual realities. The sounds and visions he gifted to we unworthy acolytes had the visceral psychic density of the most lucid of dreams.
Now David Bowie the man is gone, but he's left his creations behind to keep us all company until time and memory run out.
And if that isn't magick, then I don't know what is.
