simon and garfunkel

Two classic rock artists have become part of the day's political news cycle.

'Wednesday Morning, 3 AM' arrived as Simon and Garfunkel were still finding their inner voice, if not their actual ones.

By 1968, Simon & Garfunkel had produced a string of folk-rock hits that included ‘The Sound of Silence,’ 'I Am a Rock' and ‘Mrs. Robinson.' But their chart success brought the duo criticism from folk music purists.

Pink Floyd's legendary 1973 album, 'The Dark Side of the Moon' is one of 25 recordings to be inducted into the National Recording Registry of the Library of Congress. The record received the highest number of public nominations among this year's class.
