Gilmour can write good music. Too bad Wright was suffering from depression/drug addiction to be very productive. The best Pink Floyd songs are them working together.
Division Bell came out and took me a while to appreciate, but man I like that album as much as Dark Side and Meddle. I'm not saying they are all equal, just that I like them all equally. Gilmour is definitely my favorite bender of strings.
People are sometimes unkind to the Division Bell, but it contains one of my personal favorites: "Wearing the inside out". Wright's lyrics and vocals (first time since The Dark Side of the Moon), Gilmore's guitar, it all comes together.
