Led Zeppelin was always on the radio, or at least it seemed that way. You could flip to 94.7 WCSX, 101.1 WRIF, or any of the other rock stations in metro Detroit and hear Robert Plant's voice. In a way it made Led Zeppelin a commodity. Their music was so good it was just a given that, no matter where you were, it would be playing. It was, and still is, impossible not to feel at least a tiny bit more hopeful when you hear "Whole Lotta Love", "Going to California", or "Ramble On."
For better or worse, because their music was always on the radio, I never had any Led Zeppelin CDs. I listened to them every day anyway.
Sitting down and listening to Houses of the Holy all the way through brought back memories of summer road trips and bonfires. Most of all, it made me slow down and realize that it's all going to turn out just fine.
