I gotta go with the 60's for many reasons.
1. Motown (Motown Record Corporation was incorporated on April 14, 1960)!
2. It was like the wild west of music. Everybody was trying new stuff, and the old stuff was still goin' strong.
3. Rock and Roll was finding it's footings and growing new trees of music genres. Metal, Psychedelic, Classic Rock, Pop music, etc. were all born in the 60's.
4. The diversity of what was available was incredible.
5. The enjoyment of music was generally a communal event. People relished going to the record store (a place where you purchased discs of vinyl that would spin beneath a diamond tipped needle and, using waves in the pressed vinyl, would produce examples of the sounds individuals made with their various instruments). People gathered at venues to hear musicians play and sing (with zero studio effects and wizardry to sound just like A from era B). Interest in music was spurred by people getting excited, not by algorithms that pump to us, what will sell the most product (of that music and other products). People gathered together to listen to albums because everybody did not have any album they wanted in their pocket on their phone and in their ear with their ear buds!
6. It touched all senses. This was true in the 70's as well, but since the 80's and forward, we lost a lot in the music and all of the senses it reached. We used to smell the vinyl. With our eyes we would spend hours going over and over the album cover and it's artwork, liner notes, etc. The ears would hear the music, along with the sounds associated with dropping the needle on the record, and that blip in the record that reminded you of when your uncle was drunk and ashed his joint on the vinyl, messing up the middle of track 3 on side 2 ("It Must Be a Camel") of "Hot Rats" by Zappa. The thump of the speakers would blow out candles and cause ashtrays sitting atop them to vibrate until they fell off the edge and make your pant legs ruffle (if you had a nice system) like a good guitar cab. You could taste the humanity in every song you heard. You might not like this or that taste, but you could feel the human inside that piece of work, not like many of the studio Frankenstein pieces of today.
7. The Beatles
8. Frank Zappa ;~))
9. Motown!!
I was not able to experience this era in real time, but sure wish I had and if I ever get DOD approval to use the time machine I built, I will definitely go back to check it out, take my shoes off, set a spell!
