I'm 37 now and I grew up listening to Pink Floyd, they made some of the most interesting music of the day, once Roger Waters left the group I lost interest in them, although David Gilmour wrote some okay material, I didn't like their music nearly as much as with Roger.
As a matter of fact, I find Roger Waters music to still sound more like Pink Floyd than the last of the stuff Floyd actually did, Pink Floyd were like two groups in one, the David Gilmour band and the Roger Waters band, in my opinion the real Pink Floyd was the Roger Waters band.
Sad that he had to leave his own band to be able to make his music the way he wanted, but I know the feeling.
