On the TV screen right now, it's 1975, and Jimmy Page is playing like a man who answers to nobody. A man existing in that seductive state of extended adolescence that rock legends bask in, a man connected to something in the universe larger than even the sum total of the legendary Led Zeppelin, playing guitar because that is so clearly what he was put here to do. And it's wrong to expect that kind of divine moment to last forever, and to expect an artist to stay in 1975. Fact is, ten minutes ago I saw the guy onscreen right downstairs, coming off the trading floor of the stock exchange with a banker carrying his guitar cases for him. I sit cross-legged on the floor on a workday staring into my cereal bowl, thinking about how we all change. We all grow up. We all move on, one way or another, whether we want to or not.
