1. Hello please introduce yourselves to the readers?
Hey Patrick, and thanks for the interview! We’re Necrólisis, a thrash/speed metal band from Costa Rica, originally formed in 2002. After years of demos, lineup changes, and setbacks, we finally released our debut full-length Templo de Fraude in March 2025 through the mighty Witches Brew.
2. When did you first discover Metal music and was it long before you discovered thrash and speed metal? What is it about thrash/speed metal that drew you to this style of music?
We were first introduced to rock and metal at an early age through older siblings and friends. Bands like Metallica and Iron Maiden were our entry point, and from there we naturally gravitated to the more aggressive side of the spectrum. Thrash and speed metal drew us in because of the intensity, raw energy, and unfiltered attitude—it’s the perfect outlet for expressing rage, chaos, and rebellion.
3. Necrólisis was formed in 2002—what gave you all the idea to start this band? How did you choose the name? What is the current lineup?
Back in 2002, Sergio and former drummer Julio Díaz started the band as a way to channel their love for old-school thrash into something real. The name came from a play on words—Sergio remembered “hydrolysis” from chemistry class and thought “Necrólisis” sounded darker and more fitting. It had that rotten, intense vibe we were going for. The current lineup is:
· Sergio Velásquez – Guitar & vocals
· Tomas Campos – Bass
· Jainer – Drums
4. For readers who have never heard Necrólisis, how would you best describe the music? Who would you say are the band’s biggest influences?
Necrólisis plays raw, aggressive thrash/speed metal with lyrics in Spanish. We keep the old-school spirit alive with fast riffs, relentless drumming, and themes that deal with corruption, chaos, and resistance. Our influences include classics like Razor, Sodom, Destruction, Metal Church, Death, Violent Force, Iron Angel, and early Sepultura. But we also carry the DIY attitude of Latin American underground bands.
5. Templo de Fraude is the debut full-length released through Witches Brew—how did the band come in contact with this great label?
After finishing the masters, we started reaching out to labels that we felt were a good fit. We had a few responses, but many just never replied. Luckily, we found the contact for Witches Brew and sent an email. Cheryl wrote back in November 2024, showed interest after hearing a couple of songs, and soon after confirmed she wanted to release it. She’s been incredibly supportive and professional—definitely the right home for this album.
6. How long did it take to write the music for the debut full-length? Does the whole band take part in the writing process or does one member handle everything?
Some of the songs date back to 2006–2008, while others were written more recently. Once the current lineup came together in 2022, we spent a year shaping the arrangements, writing the new material, and preparing everything for recording.
7. Who usually takes care of writing the lyrics for the music? Which comes first—the music or the lyrics?
Sergio has written most of the lyrics and music for Necrólisis over the years. However, Tomas and Jainer have also contributed through feedback and creative input. Templo de Fraude even includes one track entirely written and composed by Jainer. Typically, the music comes first—we develop the riffs and structure, then shape the lyrics to match the energy and tone. That said, sometimes a lyric line or phrase sparks a riff idea, so it can go both ways. We’re already working on new material for future releases. Tomas has started writing lyrics of his own, while Sergio is focused on developing new riffs. Once we’ve got enough strong ideas, we’ll begin piecing together the next batch of songs.
8. Besides the full-length, does the band have any other releases or merchandise currently available for the readers to purchase? If yes, what is available and where can readers purchase it?
Yes! Before the album, we were part of a few splits with bands like Evil Force, Demonthrone, and Morbid Funeral. Those are harder to find, but Templo de Fraude is available now on CD through Witches Brew and on Bandcamp. We also have shirts, patches, and pins—fans can reach out to us directly through email or our social media for merch orders.
9. Has Necrólisis had the chance to play many live shows over the years? If yes, what have been some of the most memorable shows you’ve played? Who are some bands you’ve shared the stage with?
We’ve played dozens of shows in Costa Rica over the years. Some of the most memorable ones were the early DIY gigs in sketchy venues, as well as local festivals where we got to play alongside other bands of the national scene. We’ve also shared the stage with bands like Sodom, DRI, Exhumer and Exciter.
10. Are there any shows or tours planned in support of the debut? If yes, where will the band be playing?
Our next event is the Templo de Fraude release show. After that, we’ll shift gears and start writing new material—faster, heavier, and meaner.
11. What does Underground Metal mean to you all?
Underground metal means doing things out of passion, not profit. It’s about community, resistance, and keeping the flame alive—especially in regions where there’s no industry backing you up. It’s real, it’s raw, and it survives because people care about it.
12. Necrólisis comes out of Costa Rica’s thrash/speed metal scene—what is your opinion of the scene in Costa Rica over the years?
The Costa Rican scene is small, but very active and dedicated. Most shows happen in San José, the capital, but there are passionate fans all over the country. Local bands continue to emerge, release music, and play shows despite the lack of mainstream attention. The scene has grown a lot since the early 2000s, and there’s definitely talent and energy here worth checking out.
13. Who are your all-time favorite bands from Costa Rica? Any new bands you recommend to readers?
There are quite a few, and we’d hate to forget anyone by naming names. But Costa Rica has a long tradition of heavy music—some bands have been active for decades, others are just getting started. If readers are curious, we suggest digging into local fanzines, label catalogs, and YouTube channels focused on Central American metal. There’s plenty to discover.
14. When you need to take a break from working on music or band business, what do you like to do in your free time?
Tomas: I like to skateboard when I can, hang with friends, watch movies, and just chill.
Sergio: I enjoy reading, watching films, hiking, and diving into obscure documentaries or Formula 1 races.
15. Thank you for taking the time to fill this interview out—do you have any final comments for the readers? Thanks a ton for the support, Patrick, and to everyone reading Winter Torment. We’re stoked to share Templo de Fraude with the world, and we hope it connects with old-school maniacs everywhere. To fans, fanzines, and labels keeping the underground alive—you have our respect. Stay loud, stay true, and feel free to reach out. ¡Pura vida!
