I loved that old PBS show Connections, where host James Burke would wander around the world describing how one small invention centuries ago led to this and then that and then ultimately to some earth-shattering change like, oh, the Great Depression. He was one my guides to looking beneath the layers. But I was already on board that idea thanks to my passion for music. Reading liner notes and books LONG before the internet, I built a framework on which I could hang new bits of musical knowledge. You think you know Led Zeppelin and then you find out Jimmy Page was in the Yardbirds first! You fall for Miles Davis’s Kind of Blue album and find out that the piano player Bill Evans had a solo career as well, and you check that out, and life is never the same again.
