Mark So lives in Los Angeles, where he is a composer, musician, and organizer of experimental music events. In the last 5 years, he has written over 500 pieces, including the Ashbery, 'readings' and 'empires' series, pursuing the unforeseen in subtly reduced scenarios of musical choice and action, while exploring the space and setting of music in new ways. Mostly text-based and strongly influenced by the New York School, Fluxus and the Wandelweiser composers group, his work explores varied open "theaters" of the sensible by scoring experimental engagements with faint, passing subtleties of continuity and arrangement (time and harmony) that typically demand extreme attention, in and around changing experiences of silence. Major performances of his music have taken place around the world, at such venues and events as the Maybeck Studio for Performing Arts (Berkeley), MicroFest 2008 at the Armory Center for the Arts (Pasadena), REDCAT (Los Angeles), UC Santa Barbara (site of the 2007 retrospective mark so: late early works), Cold Storage Project (Los Angeles), the Everson Museum of Art (Syracuse), CiNE Space (New York), LISTEN/SPACE (New York), the Chop Shop (Berlin), the Lincoln Center Out of Doors Festival (New York), Kunstraum Dusseldorf, SITUATIONS: Life.Art.Transitions.Interpretations. - Maulverker Performs Music 2008 at the Villa Elisabeth (Berlin), Machine Project (Los Angeles), ROOTS/ROUTES: Performing the City at ICMC 2008 (Belfast), Galerie Mark Müller (Zürich) and CalArts (Valencia, CA), among many other performances at venues, residencies, schools and festivals throughout the world. His music has been played by notable ensembles including Maulwerker, object collection, the New Music Collective of Charleston, the California EAR Unit, incidental music, and the Dog Star Orchestra, and he has had new works commissioned by the Microscore Project, the duo Guthrie & Streb, and the Maybeck Studio for Performing Arts, among others. He has organized major public performances from the experimental tradition in the Los Angeles area, including James Tenney's In a large, open space... at Cold Storage Project, Eva-Maria Houben's Some Tunes Vol. I-III at Dangerous Curve Gallery,  and 3 concerts of works by Maulwerker performance artist and composer Christian Kesten at CalArts and Dangerous Curve. His essay “nearing/hearing” appears in the Fall 2008 issue of  The Open Space, and his extensive article “Into Silence: The Poetics of Hearing in Experimental Music since Cage” is forthcoming. He is also prolific as a performer of experimental music in the U.S. and Germany, and numerous composers have written pieces especially for him, including G. Douglas Barrett, Jason Brogan, Johnny Chang, James Orsher, Adam Overton, Michael Pisaro, Taylan Susam and Istvàn Zelenka. He appears on two recent CD releases of works by Michael Pisaro: harmony series 11-16 and an unrhymed chord, both available on Edition Wandelweiser Records.
