Arguably the greatest American rock band of all time. No other American rock band had that amount of success ever, and they did it in 4 years.. Not to mention John Fogerty didn't play music for 10 years because the label held him hostage. When he finally started playing music again in the '80s, when most thought of him as an old man, he had three or four major hits. Old man down the road, centerfield, etc. In the late 90s he put out another great album, which I believe won album of the year at the grammys. Not to mention, they are unbelievably popular in europe. And as beloved as they are, I still think they're underrated.
