[Royal Tenenbaum]

His solo work is fairly good, although Pipers was definitely the best album he did and his masterpiece. On some level, I agree, Floyd never matched this album again, but the Waters era albums are also very very good. Animals in particular is a near prefect album, and something you should seek out if you don't already have it; DSotM and WYWH are both spectacular pieces as well. You should get Barret's "The Madcap Laughs" for sure, but there is a box set called "Crazy Diamond" that contains pretty much all his solo work if you need a definite edition of it.
