Yes, after playing a song a thousand times they DO improvise or change the arrangement, as do cover bands. You heard them when Hendrix was still alive? Wow. Didn't even know he was of age at that time.
I'll ask you also: What was on the inside of the double album of Tres Hombres? It always cracked me up. BTW, I've seen and enjoyed their straight up blues/rock many times. Still listen to them. Just simple rock n roll and blues. I started with the Allman Brothers Band.
Another fun fact: I took my wife to see them here in OC back in the early 2000's. Skynard openrd for Top and blew them away. The wife (and I) were disappointed with TOP at that concert, but she has since become a life long fan of Skynard.
You got me on inside of Tres Hombres. Can’t remember. I didn’t have a lot of money back then. I would borrow records and record them on my reel-to-reel.
Allmans played the Warehouse in New Orleans all the time. I remember them playing New Years Eve and they would be jamming and it would hit midnite and they would morph into harmony guitar version of Auld Ang Syne and then morph back into something else. After Dwayne died they had his amp up there on standby. They opened for Pink Floyd in 1970. Those were good days to see concerts where the artists would take risks and surprise you.
