Did not care or understand rock and roll. All I knew at the time was skateboarding. Lucky for me older guys that skateboarded were into The Who. A perfect soundtrack for angry youth. From My Generation to Quadrophenia.
This was in 1999 decades after being made still gave goosebumps to many adolescent.
Hearing/Seeing The Allman Brothers Band for the 1st time. Prior to this I was in bands that played the hits of the day. I was never the same and never thought about music the same way again after hearin' these guys.
I was always into music and played guitar quite well but it was a hobby. I went to the Woodstock movie when it came out in about '70 and was having a great time watching but when this came on (I had never heard this song before!) it seemed like the earth shifted on it's axis. I didn't know you could "be" the music like Stills does until I saw this. I wish audio and video on youtube weren't out of sync. I've had other things make me pivot since then (Allmans Live, '60s Miles Davis, Sibelius and Debussy, etc) but this is the first thing that made me realize the power of music.
