My first impression is that it sounds a bit like the more offbeat whackiness of The Mountain, but with riffs akin to what's on Vector/Virus, but also something new I can't quite put my finger on. It's not quite as a dark as Virus, but more on par with the darkest songs from the first four albums. Something that struck me production-wise (at least from the YouTube version which is all I've heard, is how not up-front the guitars are, despite being pretty audible. That's some magic mixing wizardry there. The keyboards have tons of room to breathe.
Another note, is it just me, or does Ross sound ridiculously good on this? Something about his performance, and the way his voice is produced/mixed on this song, seems to bring out all the best from his voice.
Btw, I noticed they got Jens Bogren back on board. I liked what he did for them from The Mountain to Affinity, and this sounds even better than those by a wide margin.
