1 hour and 26 minutes, the guys had more fun making the album than we did listening to it.
It's probably among his three best solo albums, but after a few listens, as a big Pink Floyd fan, I can say that it's nothing exceptional: the lyrics are generic and uninteresting, with few emotional moment like the guitar solo in the final song, "Scattered", but his skill with voice and strings persists even at 80, and for that, only applause for this Guitar legend.
I love this acoustic version of Lez Zeppelin. "Since I've Been Loving You" is one of the best song ever and also "Tangerine" & "Immigrant Song" are beautiful. Without the last Song "Hats off to (Roy) Harper", the album would easily be a 95/100.
