Diabulus in Musica is a symphonic metal band hailing from Pamplona, the historical capital of Navarre, Spain. Formed in 2006, the band is known for blending the grandiosity of classical music with the raw power of heavy metal, a synergy embodied by the operatic prowess of lead vocalist Zuberoa Aznárez. The band's name, which translates to "The Devil in Music," hints at their penchant for dark, intricate melodies and harmonies, often employing the tritone or "diabolus in musica," a musical interval once avoided in medieval church music for its dissonant sound.

Over the years, Diabulus in Musica has crafted a distinctive identity within the symphonic metal genre. Their discography, which includes albums like "Secrets" (2010), "The Wanderer" (2012), "Argia" (2014), "Directo a las Estrellas" (2016, EP), "Dirge for the Archons" (2016), and their latest as of my knowledge cut-off, "Euphonic Entropy" (2020), showcases their evolution and versatility. With a lineup that has enjoyed stability and the collaborative chemistry among its members, the band's work is characterized by engaging storytelling, lush orchestral arrangements, and a balance between heavy riffs and Aznárez's soaring vocal lines. With each release, Diabulus in Musica cements its standing as a staple in the international symphonic metal scene.
