Well, I do like Telegraph Road. It’s a good one. It’s a long song, so it meets the criteria. I also like Kitty’s Back, it’s kinda long. Actually, there are several good fairly long songs on that old album. Back in the day I also enjoyed some of those long songs by YES. I’m sure you know the ones.
The Allman Brothers have a large catalog of long songs to choose from. Your post reminded me Tedeschi Trucks Band has some great Allman inspired jams. Love this live version of Midnight in Harlem.
My favorite Allman songs are only 5-6 mins long, what can ya do? Wrong version of that last one, here's a shorter better one
Anyone else listen to what are basically playlists on YouTube? At work I always listen to a metal or lofi playlist and especially ones with no lyrics basically turn into hour long songs. Great way to drown out the impending doom all around us to get some meaningless paperwork finished.
