Today in 1966, The Beatles shocked the world when they released their most innovative and experimental record yet, “Revolver”.
Upon release, it was described by critics as “brilliant” & is noted for changing the direction of pop music.
What’s your favorite song from the album?
An example of Bach's almost unfathomable mastery: the Contrapunctus 12 from his "The Art of the Fugue". It's a 4-Voice Double Mirror Fugue; each line in the 2nd fugue (bottom 4 lines) is a mirror image of the analogous line in the 1st (top 4). Oh yeah, it also sounds wonderful.
