Mario Diaz de Leon is emerging as a singular voice in contemporary music. With a body of work that cannot be neatly categorized, his music is marked by a sound that is both hallucinatory and intensely physical. Born in Minnesota, Diaz de Leon expanded from his early years in metal and hardcore punk to immerse himself in the work of 20th century composers Scelsi, Ligeti, Dumitrescu, and Xenakis, free improvisation, a wide range of electronic music, and noise / industrial music. Based in NYC since 2004, he completed a doctorate in music composition while also immersing himself in NYC's experimental, noise, and underground metal scenes. His debut album as composer, ''Enter Houses Of'', was released in 2009 on John Zorn's Tzadik label and praised by the New York Times for its 'hallucinatory intensity'. As a solo performer, he is active under the name Oneirogen (o-NI-ro-jen), a project known for its merging of ethereal synths, brutal distortion, and noise influences. Since 2012, Oneirogen has toured internationally and released two full lengths and one EP on the Denovali label. 'The Soul is the Arena' is the long awaited follow up to his 2009 composer debut, and the first release of his classical works for Denovali. The album's three tracks find Diaz de Leon deepening his collaboration with the core members of ICE, now a decade long. The mythological trope of the labyrinth, where a winding path leads to a central event that demands a fundamental change of direction, features heavily in the album's blend of acoustic and electronic elements, where a wide variety of ideas are unified by continuous momentum and arresting points of climax. Visionary and immersive, this is a bold body of work from an emerging master of modern composition.
