This is where I think it went downhill. Starting with the Final Cut and then with A Momentary Lapse of reason.
One of my absolute favorite albums...

When Waters took off, his solo albums showed that he's one of those musicians who needs someone to reign him in, a partner or producer.
Gilmour's Floyd showed how easy it is to fake "dark" lyrics--the lyrics stink--but even though Floyd's songwriting wasn't as strong, it still SOUNDED like Floyd. But the magic combination was gone, so it's been just a fake Floyd since The Wall (I hated The Final Cut--all gloom).
