Again - I'm the opposite! The Count of Tuscany sounds like Illumination Theory's prototype. Like they were getting somewhere with it, they were writing along the right lines, you can hear the germ of a concept that would later become Illumination Theory, but they didn't quite achieve that for another few years. Illumination Theory, for me, is like The Count of Tuscany with the creativity, invention and madness cranked all the way up to eleven.
I mean, that's an oversimplification, and a shorthand - in truth, they're just two heavyish songs with ambient midsections, the outskirts couldn't be more different - but those ambient midsections are central, so it's not entirely superficial. I feel like Illumination Theory is innately epic, where every last moment is essential to the next, whereas The Count of Tuscany is a (completely badass!) verse-chorus-verse-chorus type rocker that spiralled out of control.
