Gilmour had a record before About Face that was self-titled, but it wasn't as good as About Face. The best track on it was called "There's No Way Out Of Here." Also, his newest release 'On An Island' is alright; very atmospheric, but boring at times.
However, I find Roger Waters's solo career to be more interesting and productive. His first solo record, The Pros and Cons of Hitchhiking, was very good, and very Floydian. It also had Clapton playing lead guitar!
His next release, Radio KAOS, was good, but very 80s. Still, it had some great tracks, like "Home" and "The Tide is Turning."
His last solo rock release was called Amused to Death, and it's one of my favorite records of all time. The whole thing is a concept album about how modern society has "amused itself to death." The whole album is great, but some standout songs are the title track, "It's a Miracle," "Watching TV" and "The Bravery of Being Out of Range." The record also has Jeff Beck playing lead guitar.
Most recently, Waters released a solo record called Ca Ira (There is Hope). It's a completely symphonic concept album, opera style, about the French Revolution. If you like classical music and opera, you'll like the album. But it's not typical Floyd/Waters stuff.
Pink Floyd is my favorite classic rock group, so I try and collect all that I can of their stuff. They were an amazing group, and all of them were great musicians. However, if you're looking for solo stuff, I'd recommend Waters over Gilmour. Give it a listen!
