My favorite Pink Floyd album, Meddle, is probably the one Floyd album on which Wright is most prominent. I've always thought he was underrated as a creative force in that band.
I'd argue (though not in an argumentative fashion) that Wish You Were Here displayed Rick's contributions most prominently (particularly in the back end of Shine On where several sections were dominated [probably too strong a word for him] by Rick).
Meddle/Dark Side/Wish You Were Here... What a legacy for an artist!
I enjoyed Rick's solo work as well - made a high-quality cassette with Wet Dream on one side and Gilmour's 1st solo on the other and it got lots of play on long drives and at home. (Can't say the same for Pros and Cons or The Final Cut for that matter.)
Damn - I was even a fan of those early wistful PF pop songs of his - loaded with melancholy: Paint Box, See-Saw, Summer 68...
Pink Floyd was my clear favourite band and Rick was certainly a huge inspiration for me. RIP Rick.
