If Magritte can paint not a pipe why can't I photograph not a tree? And why can't I ask Magritte that question? I can imagine Magritte tipping his bowler hat and saying " 'scuse me while I kiss the sky." Or not.
I'm listening to Jeff Buckley's cover of "Hallelujah" while I post this. I heard it for the first time today and is one of my favorite recordings ever. It was number 1 on the Billboard chart 11 years after his death.
