First time I heard it, I was blown away. Their other Rush-inspired songs were like let's get an element of Rush then plug it into a precomposed song but this is one is different. The composition here is more meticulous, there is no sense that they are just plugging in Rush elements because the parts of the song flowed so well into each other. Even the way they played was different from the usual: Mangini, Jordan, Myung. I can imagine Mangini actually smiling while playing this like a kid finally doing a Rush tribute that is not a Rush cover (and he already did around 14!).
I was smiling listening to this from the start but I really fell hard for this song when James sang "...like dreaming wide awake." That was when it really felt this was something special.
