If you turn 21 today you share a birthday with Face the Nation, “the third and final album by hip-hop duo Kid ‘n Play.” Oh, also a record called Nevermind by some band out of Seattle. Yes, that’s right, Nevermind is as old now as The Carpenters’ Close to You was when Nevermind was released. You know what else came out 21 years ago today? The Red Hot Chili Peppers’ Blood Sugar Sex Magik, the final album of their “credibility” period. 1991, man. They say if you can remember it you’re old now.
