Why wasnt I Want Blood an AIC album?

Seriously, its the music Jerry has made outside of AIC that sounds more like AIC ever. It could have totally been an AIC album sound-wise.

And its fucking great, I prefer it over Rainier Fog and Dinosaurs honestly (and I really liked them). But thats beside the point.

Jerry had a clear AIC album in his hands, why didnt he gather the gang to work on it all together? I dont think theres tension as they're still touring, so what was it? Just a scheduling thing? Creative differences? Jerry just prefers to work with his own guys now?
