Back in 2012, the Marvel Cinematic Universe changed the game and shook the industry with the release of The Avengers, a years-in-the-making blockbuster that brought all their disparate heroes together on the silver screen in a historic first. An approximate $1.5 billion later, and suddenly everyone else wanted a money-making universe of their own. DC Studios fast-tracked an Extended Universe; Fox brought back Bryan Singer for 2014’s X-Men: Days of Future Past, which saw OG trilogy stars reprise their roles alongside the new blood. Universal, the original maestros of the crossover universe, jumped back into the game with the Dark Universe, an especially ill-fated attempt that perfectly illustrated the folly of such heedless trend chasing. Hell, even Daniel Craig’s Bond tried with a series of interconnected films. Nowadays, the very mention of a connected universe is enough to elicit a solid groan from people who enjoy actual films over slop. This shit is exhausting. I have a job; I shouldn’t have to do more work to watch a movie. So, when I read the words “Welcome to the Calva Louise Universe” on UK metallers Calva Louise’s Bandcamp, you best believe my groan was mighty.

A three-piece with their own Avengers-esque story—that of unlikely compatriots drawn from disparate corners of the world for an ultimate purpose—Calva Louise is the collaborative brainchild of Venezuelan Jessica Allanic (vocals, guitars), Frenchman Alizo Taho (bass), and New Zealander Ben Parker (drums). Their albums tell a sci-fi story conceived by Allanic when she was younger, following a woman named Louise who discovers a mirror world beyond our own, populated by “Doubles.” Edge of the Abyss is their fourth LP, and my first experience with the band. With a sonic cuisine bringing together razor-edged metalcore, sci-fi electronica, art rock, and a charismatic frontwoman in Allanic, Calva Louise has the sort of core ingredients known to hook my tastes. But, can a first-timer like me survive such a plunge into the cinematic abyss, sans homework? Or do I need to spool up a subscription to Calva Louise+ for further education?

Put down the credit card and unroll those eyes: Edge of the Abyss is not only a stand-alone experience, but an exceptional one at that. While I’m certain there’s connective threads to prior albums linking all of this grand dimension-traversing narrative together, one may safely leave that at the feet of the Calva Louise lorekeepers. Packaged here are eleven tracks and forty minutes of absolutely gonzo, balls-to-the-wall progressive metalcore shot through a multiversal portal of Latin American rhythms, dance-hall-club thumpers, and an uncorked vocal performance to rival Poppy’s most schismatic aural shenanigans. Allanic goes full Bruce Banner / Hulk, delivering saccharine-inflected, almost playfully psychotic cleans reminiscent of bubblegoth-era Kerli before jumping into the purple pants to unleash an arsenal of razored screeches and some surprisingly thunderous lows. Like Poppy, Allanic changes styles at the drop of a dime, made all the more impressive when she switches fluidly from English to Spanish across the majority of Edge of the Abyss. There’s some real psycho-mania energy on display, as if Allanic’s performance comes from a mind ruptured by secrets not meant for mortals. Whether swaying into a sing-along verse (“Barely a Response”) or spitting out vocals like broken teeth (“WTF”), Allanic lands every stroke of her deranged performance with serious aplomb. Her guitar work impressively matches the lunacy via a skronky mathcore-esque freneticism.

If Allanic is the Tony Stark of this outfit, Parker and Taho are Captain America and Thor. Parker provides an especially fluid performance on drums, conducting the album’s rhythmic aims like a meth-addicted octopus as he rolls, blasts, and rides across the kit. He’s thick and punchy in the mix, standing toe-to-toe with Allanic’s churning guitar, knowing when to let a simple beat ride and when to start rolling bones under his double-bass. Taho’s bass playing gets lost in the shuffle on the album’s louder moments (one of the only metal sins Edge of the Abyss commits), but his tones are warm and resonant when audible, thrumming like a steady current to power the madness. Meanwhile, guest contributor Mazare steps in with Hawkeye-level assists, backboning and accenting the record with a slew of dancey beats and skittering keys that add to Edge of the Abyss’s eclectic—and unfettered—fun. The Latin American flavors are integrated well into this glitchy, chaotic stew, feeling authentic and purposeful rather than tacked on for “prog points.”

Metalcore has a tendency to get staid and repetitive, following a very tight structure emphasizing (if not entirely built around) breakdowns and uplifting, cleanly-delivered choruses. A good time, but whole albums can be hard sells for those not entirely beholden to the genre’s whims. On the opposite side, bands like The Dillinger Escape Plan or the aforementioned Poppy can be difficult commitments for me due to the mania that drives their sounds. I can get down with unhinged vocals and whiplash time signatures, but an entire album’s worth runs the risk of grating on my nerves. There’s a novelty factor at play, too, the threat of a “gimmick” overriding the listening experience. A band has to have something more guiding them; strong songwriting, variety, solid pacing… any and all of these go miles towards taking the parlor trick of “we can play 350 bpm” and transmogrifying it into an album you actually want to sit with.

Calva Louise might have easily fallen into this pit of wacky novelty, and I fully expected them to, on first listen. Yet they defied my odds with Edge of the Abyss. Every song has a life all its own, refusing to repeat ideas or fall into genre tropes (no wasteful intro tracks here!). Perhaps this sounds silly, but there’s a scrappiness that translates through the music, a DIY ethos which, despite the modern production, empowers the band’s efforts. Calva Louise sound hungry on Edge of the Abyss, like a tenacious creature throwing everything it has at survival. I’m reminded of early efforts by acts like Slipknot and Mudvayne—not sonically, but spiritually. A vitriolic commitment to artistic vision, in defiance of outcome, is something I’ve long admired. That Calva Louise is four albums deep and able to conjure this kind of energy is delightful.

Like when I sat down recently to watch Marvel’s Thunderbolts*,¹ I stepped into Edge of the Abyss stuck somewhere between frayed hope and pre-loaded disappointment. So far, 2025 hasn’t been the best year for new metal releases; barring a handful of standouts, most of what I’ve heard has sat well within the “okay” to “decent” territory—and much like Marvel’s output of the last decade, I was starting to get a little numb to it all. Luckily for me, hope won the day on both accounts.² Calva Louise was far more than I expected, an energetic, multicultural detonation of influences with an origin story befitting a Stan Lee “Excelsior!” Full of twisting genre shifts, infectious melodies, and one of my favorite vocal performances of the year, Edge of the Abyss is a precipice I wholly recommend pitching oneself into.
