Being a regular reader of both his blog and his work at the Village Voice, I am always impressed and often stunned by Roy's facility in pop culture (among many other topics). In comments, perhaps less guarded, he is the man that puts fish hooks into your brain.
Starting with a classic Sadly No! post by Gavin he sparingly riffs. If you don't know Capra or the running faux-controversy of Barry's birth certirficate or the beautiful music reference that I can't pin down it may not seem so amazing. But for fuck's sake, I only get two out of three and it is art.
Jazz is to music what this is to writing.
