I sort of agree, but after The Final Cut when Gilmour took over (i.e. momentary lapse of reason era), they were equally as bad, and the lyrics were especially lacking. They produced their best work in the wake of Barrett's mental breakdown, when they all worked together. A 6 year golden period for Floyd, from Meddle to Animals. Without Waters we wouldn't have the lyrics, no solos or good guitar work without gilmour, no great gig in the sky or welcome to the machine without wright, and Mason is obviously a boss but the drummer never gets any credit.
The Wall is such a crazy and fucked up album, it really tells the story of itself, i.e. band leader turned megalomaniac patronizing and looking down on his fans. Kind of a really dark, self-fulfilling prophecy. Of any band Floyd has one of the most colourful and interesting histories.
Have to agree though, On an Island is dope. 10/10 for you sir (for this post and your response to my science thing).
OK I'm done.. Back on topic.
