@augustus I can respect that ranking. I always kinda disliked Gilmour, he's a talented guitarist, but his songwriting is boring as hell.
Barrett was the most creative of all of them, acid or no acid; it's a shame he went nuts, but we can't change the past. Waters was also very good, if a bit of an egomaniac; although I have to respect him for his anti-war, anti-Zionism, and pro-Assange activism, he's a standup guy.
