Eliza Brown

Assistant Academic Dean, Young Musicians Program

Composer Eliza Brown attended the Walden School as a YMP student from 2000-2002 and has since returned for many years as a staff and faculty member.

Deeply interested in the relationships between music and the other arts and humanities, Eliza has also engaged in interdisciplinary collaborations with practitioners of theater, dance, architecture, painting, and film, frequently taking on other artistic roles in these collaborations in addition to “composer.” Eliza holds a D.M.A. in composition from Northwestern University and has taught at Northwestern and Columbia College Chicago. In fall 2016 she will join the faculty of the DePauw University School of Music

Alex Christie

Assistant Academic Dean
Director of Composers Forums, Young Musicians Program

Alex Christie makes acoustic and electronic music in many forms. His music has been called “vibrant”, “interesting, I guess,” and responsible for “ruin[ing] my day.” He enjoys collaborating with artists in all fields and is particularly interested in the ways in which acoustic and electronic sound worlds intersect and inform each other. He has spent many years turning his laptop into a musical instrument capable of improvisation and real-time, expressive musical gesture. He is attracted to hyperactive sound and bright, flashing lights.

Alex began his compositional career many years ago as a student at Walden’s Young Musicians Program where he now serves as faculty and the Director of Composers Forums. He has taught at Santa Clara University for the past five years, but is leaving the school and California to pursue a PhD in Composition and Computer Technologies at the University of Virginia where he has been awarded a Jefferson Fellowship. He enjoys baseball and geometric shapes.
