Marissa Deitz (b. 1990) is a composer and performer located in Oakland, CA. She works in electro-acoustic composition, multimedia and live video processing, and dream-pop songwriting under the moniker Sucker Crush, and has performed nationally as a cellist, vocalist, guitarist, improviser, and electronic musician.  Deitz is a recent recipient of an MFA in Electronic Music & Recording Media at Mills College, working with James Fei, Fred Frith and Pauline Oliveros. She also holds a BM in Music Composition from Columbia College Chicago, studying under composers Drew Baker and Marcos Balter. 

Her work reflects the manifold influences of her musical upbringing, thriving at the intersections of popular and contemporary classical music in ways that are not only based in genre but engrained in the compositional and social approaches to these musics. Deitz's current pursuits address her critiques of contemporary classical music while harnessing its attitude of experimentalism and technical excellence.

Recent projects include a national tour and impending record release with Sucker Crush, individualized guitar improvisation for the SFMOMA Sountracks Exhibit by Chris Kallmyer and Mark Allen, music for the critically acclaimed indie games Little Party and FOREVER TRANSIT AUTHORITYA Portrait in Greys commissioned by cellist Bryan Hayslett, and Close Inside Mine commissioned by Ryan Muncy and Amanda DeBoer Bartlett of Ensemble Dal Niente. Past projects include the founding of indie tape label Other Coast, the release of two albums with acoustic chamber pop group Wooden Rings, avant-pop duo The Vale, and Fantastic Animal, her multi-media and multi-movement exit project from Columbia College.
