I tend to like the more upbeat King Gizzard albums, but when they rock out, they usually fixate on a groove and ride it for several songs straight. This makes for some really good moments mixed with long stretches of repetitive, monotonous jamming as filler. The more varied and psychadelic-leaning releases trade in that energy for really hot melodies, but the variety is such that I end up finding two or three favorite tracks and ignoring the rest.This album takes the best of that upbeat energy and hones it into a metal frenzy with tracks that rip from start to finish. And then somehow each song sounds significantly different from one another while channeling a common metal theme. Homages to Slayer, Black Sabbath, and Pantera abound in a chugging, thrashy mix with Motorhead-inspired vocals. I never thought I'd hear a King Gizzard album that resists self-indulgence as hard as they do on this album, and the music is all the better for it. In fact, the only negatives I have for this album come from when they fail at parodying metal by rhyming words that end in "tion," talk too much about pastry, or start going off on some weird cosmic journey. Luckily, I think they knew that this had turned into something special, so the "cute" lines are rare or actually challenge metal tropes in a really positive way. "Partly smart, partly art, partly not."I cross my fingers for another album this tight from King Gizzard. Or another metal extravaganza. But, I don't expect it. This album is great and that's all it has to be.
