The animosity between Kuepper and Bailey, post-Saints has been legendary. Think Lennon/McCartney, Lydon/McLaren and Reed/Cale rolled into one. Much of it stems, apparently, from Bailey's continued use of the Saints moniker, hence Kuepper forming the Aints
As to arguments of superiority, jeez, that's a toughy. What can't be argued, though, is Kuepper's productivity. At one stage, around 92-93, he put out 7 albums in under 2 years, and all of them great. A nightmare for fans with limited budgets.
There's a full discography on his website
, but it doesn't seem to have been updated in the last couple of years.
As to indispensible Ed Kuepper records: Another tough one. I'd say probably the Laughing Clowns "Law of Nature", containing the magnificent "Eternally Yours", as well as "Today Wonder", "Honey Steel's Gold", "Rooms of the Magnificent" and "Character Assassination".
He also has a couple of Best Ofs out: "The Butterfly Net" (1985-1992), "Ed Kuepper Sings His Greatest Hits For You" and also a Greek compilation "Heart of New Wave" (1983-1995).
