For those of us over 60..

The Beatles. 

'50s: Chuck Berry, Fats Domino, Buddy Holly, Lloyd Price'60s: Ray Charles, Janis, Santana'70s: The Band, John Fogerty'80s - present: Americana in general with a tip of my hat to John Fahey

Classical is another topic for conversation...

I think it all depends on the year for me.  So many great artists from year to year makes it impossible for me to pick one group to define 72 years on Earth.

Oh man, I’m only 54 and all this seems completely beyond my time old-guy stuff ;-)

Allman Brothers, Grateful Dead, Moody Blues....*shudder*....

Not long ago I tried watching some Grateful Dead concerts on line, just to see what the fuss was about. I sure couldn’t figure out what the fuss was all about, nothing even remotely compelling. Seemed like a scrappy old band  outputting bland music.   But, hey, I guess they just weren’t my idiom. I like tons of stuff many here would think of as WTF? So that’s how it goes.

The Beatles, their catalogue pretty much covers every emotion and experience. (To digress, a big thumbs up to Egypt Station. Ear worm galore.)
