I both agree and disagree on a few points.
I felt Allegiance was by far their best album to date, and I don't feel The Premonition is nearly their heaviest album to date, possibly the least heaviest on the whole if you ask me. I actually feel for the most part like The Premonition comes off like a weaker version of Allegiance.
I do think it's a very good album, and I too noticed the Dio and Police-isms on the respective tracks you mentioned them for. And yeah, the Maniac cover is both surprisingly metal and surprisingly good.
