I've heard the whole album now. After only one playthrough, I think it's probably their overall least heavy album. There are some heavy tunes for sure, Silvera being the heaviest, but mostly this album is wide open with lots of trippy melodic stuff going on. LOTS of clean vocals which I didn't expect and NONE of those awesome Gojira signature pick slides they used on every album before this one.
The progression this band seems to be entering reminds me a lot of how Mastodon grew over time. Started out heavy and slowly got more melodic and psychedelic over time. This is still a good album but right now I think it will need to grow on me a bit before I truly love it. Same thing happened with their last album. Sort of disappointed, but also sort of expected this so it's not a loss at all. No band really ever stays exactly the same when they're around as long as Gojira has been. If they do, they usually get boring so ultimately I think this will be a good thing.
