Doomed Confessionary: Elvio, Rodrigo & Daniel (Triangulo Negro)

Triangulo Negro is a heavy psych/stoner rock trio hailing from Rosario, Argentina. Formed in 2014, the band currently consists of Elvio Valdés on guitar, Rodrigo Ortiz on bass, and Daniel Tenaglia on drums.
Triangulo Negro’s music is largely instrumental, built heavily around a groovy, rhythmic punch and distorted, psychedelic guitar tones. Their sound heavily channels classic stoner metal and 1970s psychedelic heavy rock.
They released their second full-length album »El último árbol« on January 8th, 2026. Mixed and mastered by Cristian Dalessandro. Artwork by Belisario Gronda. »El último árbol« is available now on all major streaming platforms.
