Led Zeppelin

I'm reviewing a bio of the dread Zeppelin and realizing that they were my first foray into sophisticated music. Laugh if you must but they went far beyond the simple textures and orchestrations that I'd been listening to up until then. They, more than Pink Floyd, were the Radiohead of the 70s. Except that they were so much better than Radiohead (Wait, maybe that means Radiohead was the Pink Floyd...).
