Evolution of Music, a Cappella...

I recognized everything up through the 1970s, and maybe half of the 1980s.  Everything after that was new to me (and didn't make my ears happy!).

When I was a teenager, I was astonished when my parents forbade me from playing Joni Mitchel or Simon & Garfunkel on our family's record player.  It was easier for me to understand why they didn't want to hear Crosby, Stills or Jimi Hendrix.  They must have felt then as I feel today listening to this music of the 2000s...
