"#nowplaying Dream Theater - Dream Theater. Massive sense of anticipation here at Prog Towers!!"
"First impressions: different to A Dramatic Turn of Events. Heavier and also more melodic. Some lovely obtuse time changes and very proggy in places. The epic Illumination Theory will thrill DT fans. It won't change opinions of the band's detractors within the prog community, and these are still early days, but it sounds like a strong addition to the band's body of work."
