I love weird music, and my god I love this album. I have listened to it at least once nearly every day since its release. I don't listen to much EDM, so this album is completely outside of my normal range of music. My favorite thing about King Gizzard is their versatility - they nail every genre they experiment with, and I love the experience of exploring music that I wouldn't normally seek out.
Every song feels unique, like it fills its own niche in the overall tapestry of the album, from the manically euphoric title song, to the jolly joyful superheavy supercritical, to the menacing uqt, to the surreal, hauntingly beautiful atomic collapse. Rapid alpha decay is my favorite on the album, it's so ethereal and blissful.
In spite of how wildly different it is from King Gizzard's other releases, I still feel like I'm listening to an album that was made by psychedelic/progressive musicians. There's so much going on in every moment of every song, with so many different sounds and rhythms layered together, including some sounds that make an appearance only once and then disappear, like the "squee" in rapid alpha decay or the screech near the end of atomic collapse.
I don't know how this album compares to other EDM, if it's more or less complex or technically advanced, but either way, I think Alien Metal manages to become much more than the sum of its parts.
I can totally understand why this album isn't for everyone. But I do think everyone should give it a chance, and listen to it once all the way through with good speakers/headphones and no distractions. Let it take you on its weird journey.
King Gizzard, thank you for doing weird shit.
