Query: The golden age of nostalgia

15 Big Ones is an album made in desparation when the Beach Boys realized that they had become a nostalgia act. (I suspect they also had problems with their publishing contracts at the time.) It consists mainly of a lot of weird covers of songs they wish they had recorded earlier."The Beach Boys Love You" is a far more interesting work: Brian Wilson returned to the studio with the rest of the guys during one of his rare period of lucidity and recorded a collection of truly unique songs which he had written while the other Beach Boys were off on the nostalgia circuit. My favorite is "Solar System"-- a joyful celebration of, yes, the solar system.
