François Couture, All Music Guide--"Since the mid-'90s, Ernesto Diaz-Infante counts as one of the most prolific avant-garde composer and improviser the U.S. West Coast has seen. He has performed and recorded music on piano, prepared guitar, and electronics; composed chamber music; improvised with a very large number of musicians from California, New York, and Chicago; and released a pile of CDs on very small independent labels such as Pax Recordings, Sweetstuff Media, Zzaj Productions, and Public Eyesore. His multifaceted career gives him the look of an eclectic or maverick artist, but the persistence and commanding seriousness with which he pursues his career is gaining him a small but dedicated following."

In 1997, San Francisco composer/guitarist Ernesto Diaz-Infante began the Pax Recordings record label which is dedicated to the documentation, preservation, and contagion of music from the margins of our culture and psyches. He and filmmaker Marjorie Sturm run Pax Recordings.
