I recommend starting with short stories. "Space, Time and Nathaniel" and "Moment of Eclipse" are both great collections. Or just "Best SF Stories of Brian W Aldiss", which I think was updated several times -- that's how I first found him.
His novels are mostly excellent but I think there's a good chance you'll bounce off them if you don't happen to like the Aldiss vibe. He can appear very cold and dry until you realize how funny he (usually) is.
