Paul McCartney’s slightly vertigo-inducing video for “I Don’t Know” is one of my favorite tracks on his new album, Egypt Station. It’s not a great album, and could have used some trimming, I think, but there are gems, and this is one. Paul often gets dismissed for, well, silly love songs—specifically by John Lennon, there—but mostly by those who consider he’s forever cranking out sunny fluff. But he’s got a darker side, his share of gloom, and those songs are found throughout his oeuvre.

It seems a piece with some of his later work where he addresses being older, having a sense of his own mortality. Self-examination is important for all of us, especially those of us making things. We put our hearts into the work, and without knowing the dark side as well as the light, we aren’t approaching it with our complete selves.
