When I was young and impressionable, the "bad" kids listened to AC/DC. Sitting at the back of the school bus, looking just a little scruffy, with Led Zepplin, Nazareth, Sabbath and AC/DC emblazoned on black tee-shirts.

The rest of us murmured rumors that if you played Stairway to Heaven backwards, there were subliminal satanic messages encoded. As for AC/DC, you didn't even have to play the songs backwards.

I don't know when my attitudes shifted, but somewhere in my twenties I discovered that Led Zepplin was in fact the best darned music anywhere. I even developed an appreciation -- if not quite a passion -- for the energy in AC/DC.

Now in my late thirties, my mood has shifted again. AC/DC now sounds .... nostalgic, for lack of a better word. Hell's Bells gives me a warm fuzzy. Sort of like the "awwww..." I feel hearing the first chords of Simon & Garfunkel's 59th Street Bridge Song.

It's highly incongruous, but there you are.
