Mario Diaz de Leon

Core Lecturer, Music Humanities

Mario Diaz de Leon, Core Lecturer in Music Humanities, has written a body of modern classical works focused on acoustic / electronic hybrids, often expressed as hypnotic walls and gestures of shimmering sound.  His influences include the composers Scelsi, Ligeti, Dumitrescu, and Xenakis, free improvisation, underground metal, a wide range of electronic music, and noise / industrial music. .His works have been described as "21st century chamber music that couples crystalline clarity with the disorienting turbulence of a sonic vortex" (Wire Magazine).

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”.  He has written extensively for the ICE and Talea Ensembles, and his works have recently been performed at the Venice Biennale, Lucerne Festival, Musica Nova Helsinki, National Gallery of Art (DC) and Roulette (Brooklyn).

His works have recently been presented at Chicago Symphony Center, Hakuju Hall (Tokyo), Venice Biennale, Lucerne Festival, Musica Nova Helsinki, National Gallery of Art (DC) and Roulette (Brooklyn).  In 2016, he was commissioned by the Los Angeles Philharmonic to write a new work for brass and electronics.

As a solo performer, he is active under the name Oneirogen (o-NI-ro-jen), an experimental project known for its merging of ethereal synths, brutal distortion, and noise influences. Since 2012, Oneirogen has released three full length LPs and two EPs on the Denovali label.

Born in Minnesota in 1979, he grew up playing guitar in hardcore punk and metal bands before attending the Oberlin Conservatory of Music, where he studied electronic music and composition.  He has lived in in New York City since 2004, and received his doctorate from Columbia University in 2013.
