You're not a jinx for Rival Schools, I can tell you that much.
Walter Schreifels is an amazing artist, but his list of bands that were bitchen and then disbanded just got one band longer. Gorilla Bisquits, Quicksand and now Rival Schools. He's already playing with a new band Walter and the Motorcycles (I think) and I'm sure they're great. They won't be Rival Schools because Ian was an amazing guitar player, but check them out and you miss Rival Schools that much.
When I called my bro about RS, he said "Haven't heard, but it wouldn't shock me. I'm sure he's already on to a new project."
By the way, I'm stoked you like RS - I didn't know anybody else on this board liked them. While they've enjoyed a lot of success in England, the Brits on this board follow more pop and less punk from back home.
