I don't know if the band is the most underrated of all time. That's saying a lot. But I'll say that Mark Knopfler is one hell of a guitarist (chicken picker)!
I've always like Pink Floyds music - until I watched their Pigs concert on YT with all the USA and Trump bashing.Sailing to Philadelphia AVO session on tube is one I like. How about this; Pink Floyd was the most innovative/genius band of all time..?
Thanks for mentioning BTO - haven't thought of them is a while.I never cared for zep, the radio run stairway to heaven in the ground back then along with free bird. back then i liked BTO and Black Sabbath way better than them.
