Stimulating  performances...interpretive richness, athletic vision, filled with angles, edges and sound surfaces…Technically surprising…Numerous moments of shining resonances…

—John Arturo Brennan, La Jornad

Onix Ensamble is an extraordinarily talented group of Mexican musicians dedicated to bringing to audiences the finest performances of contemporary music from Mexico and Latin America.  Based in Mexico City, Mexico, all members of  Onix are internationally acclaimed musicians and soloists in their own right.  Onix is recognized for their virtuosity and innovative musical interpretations.  

Dedicated to the principles of high quality musical craftsmanship, artistic originality and cultural diversity, Onix was founded in 1996 by Mexican musician and new music advocate, Alejandro Escuer.  Onix delivers a unique panorama of exclusive works which are often influenced by literature, theatre, visual arts and new technologies. The emphasis is on original interpretations of works by Latin American composers such as Mario Lavista, Alejandro Cardona, Michael Nyman among others who are interested in expanding and developing musical idioms.  

Onix’s repertoire spans a wide musical spectrum, ranging from the most recent trends in new music to classics of the 20th century.  

Onix has collaborated on projects both nationally and internationally that have resulted in recordings, world premieres, residencies and projects.  They have  released five CD recordings and premiered many new works by composers written exclusively for Onix.  They have toured extensively in Mexico, the United States, South America and Asia.
