Fisión Nuclear: Libres De Todo Mal | Nuclear Energy And Its Laws
(2025 – Metal Command)
The topic of nuclear energy has been in vogue lately. Well, anything related to nuclear energy and its derivatives never ceases to be newsworthy. Some believe that nuclear energy could be the salvation or downfall of the world, or even a good excuse to bomb you mercilessly. Fisión Nuclear thinks otherwise, and with their new album, they propose that we free ourselves from all evil.
Thrash metal is a style that never dies, surviving in underground spaces and always coming out on top somehow. Argentina in particular is a country where the genre has always subsisted in underground spaces, perhaps the place where thrash metal tends to shine and come out on top.
As is our custom, we tend to review what’s out there that never makes the headlines, and that’s how we came across this album by Fisión Nuclear, a band from the southern part of Buenos Aires with a fairly extensive history in the Thrash scene, with a first album released in 2022, an EP, and a live album.
“Libres De Todo Mal” is the new release from Fisión Nuclear, and a good excuse to get to know this band, which focuses on old-school thrash metal but, as we will see, has a wide range of influences that take their sound down perhaps unimaginable paths and demonstrate their freedom from the clichés of the genre.

Right off the bat, we can say that Fisión Nuclear draws on everything that is thrash metal, and this is confirmed from the first track, entitled “MJ-12,” although it is actually the second track, as “U.F.O.” is an instrumental intro. Power, energy, and thrashy rawness from the very beginning, but with unexpected melodies in the choruses, is what Fisión Nuclear offers from the get-go.
“Memorandum” continues in the same vein, with the same rage and fury, with introspective guitar passages and solos that seem unrelated but demonstrate the band’s versatility. The instrumental “5/5” is incredible, clearly inspired by classical music, taking thrash metal to its more musical and less virulent side. Its riffs, solos, harmonies, and melodies are truly enjoyable.
Almost like film music, “Bufalos” serves as an introduction to “Estampida,” a real punch to the chin, energetic and crushing. In contrast, “Montag” seems like an attempt to take the genre in a more progressive direction, so to speak. Inspired by Guy Montag, the iconic character from Ray Bradbury’s novel “Fahrenheit 451,” its changes in tempo and intensity make it one of the most interesting tracks on “Libres De Todo Mal,” which coincidentally is the next song that begins with an intro that sounds like a sermon but tells a few truths, and takes us through all the fury of thrash metal, at full speed and spitting out what could be described as a battle cry.
“Del Mar” is the ballad of the album, melodic and pleasant, loaded with feelings that emanate from each of the notes and heart-wrenching chants. Finally, “La Maldita Ola Amarilla” focuses on the sad social and political reality of Argentina. A cry of fury and protest to close an album that ultimately shows a different side of what Thrash Metal can be.
Fisión Nuclear does not limit itself to the Thrash genre; its sound is strengthened by elements ranging from traditional Heavy Metal to clear inspiration from classical music in many of its compositions. “Libres De Todo Mal” offers freshness and oxygen to the genre, not staying within what many of us already know, but expanding the panorama of Thrash without falling into the trap of adding modern or trendy elements that are currently popular in the world of Metal.

Fisión Nuclear’s sound is basic, fast, and furious, but with a different foundation than what we already know. This is where the band stands out and demonstrates a versatility in their songwriting that sets them apart.
The cover of “Libres De Todo Mal” follows the “nuclear” theme of the genre and even matches the band’s name. Graphically, the best part is inside the booklet, where the illustrations accompanying the lyrics of the songs are in keeping with the chosen theme, which revolves around different personal, social, and political issues, as well as recalling a major literary work, as in the case of “Montag.” And of course, there are also several photographs of Fisión Nuclear.
As for the final sound, there are no surprises, but it is worth noting that it is ruthless and almost natural in its structure, without unnecessary embellishments, emphasizing the heavy riffs and guitar sounds with a strong, powerful base and without too many effects. The album was recorded between 2023 and 2025 at Samurai Studio, and it is worth noting that it is a completely independent production.
Fusión Nuclear is a breath of fresh air in the Thrash Metal genre, and with “Libres De Todo Mal,” they demonstrate their evolution and potential to be more than just a simple Thrash band.
