If I can figure out how to make the Box widgets work I plan to make this a regular feature. Until then, go read about the stagnant state of rock:
Sometimes it seems rock is the most conservative music on earth. Mozart's Symphony #40 is dated 1788. Beethoven's "Ode to Joy" was completed in 1824. In 32 years, working in the same genre with the same musical form and the same orchestra, look how the geniuses re-invented the whole notion of music!
OK, "Rock Around the Clock" is released in 1954. Add 32 and you get 1986. Take away arrangements and production, and for my money there's not an inch of daylight, musically, between "Rock Around the Clock" and "Walk Like An Egyptian." Stripped down to just lyrics and chords, they could be from the same year. In fact, a Haley recording of "Rock Around the Clock" charted at #12 as recently as 1974 (When "American Graffiti" was hot).
