I was a teen in the '70s. I didn't pay a great deal of attention to the rock bands of the day. I was an advanced piano student and played all the "classical" things, and that's mostly what I listened to, as well. But I heard contemporary songs here and there, on the radio, or with friends, and now when I listen to '70s songs on Pandora, I need look at the screen to see what band is performing it. I recognize many songs, but have no idea who performed them!
