Artistic duo La Monte Young and Marian Zazeela’s immersive “Dream House” is meant to be experienced, not just visited. Zazeela and Young, who are married, have been working together for over forty years, and first started “Dream House” in 1993 in an apartment on Church Street. The environment features drone-like music by Young and lights and sculptures are by Zazeela; the lights and sound change based on the visitor’s movement. Staying inside for a long period of time might cause dizziness or discomfort, but the artists say that the environment is meant to create a trance-like existentialist experience.
