I really enjoyed visiting the Dream House, though I think I listen to enough weird music that it wasn't the case that "all the sensory information [was] unusual and outside [my] normal frame of reference."
The scene behind Dream House is fascinating. La Monte Young and Marian Zazeela were at the center of the 60s downtown art scene. John Cale (of the Velvet Underground) played viola in Young's Theatre of Eternal Music before forming the band. They also at one point had $150,000 in unpaid rent. A fascinating rabbit hole if you're into minimalism and atonal music (and other similar pretensions).
