Artists Mel and Dorothy Tanner began experimenting with immersive experiences decades before it hit the mainstream, starting in Miami in the late '60s. Although the Tanners have both passed away, their legacy is kept alive at Lumonics Light & Sound Gallery, which opened in Denver in 2008, by Marc and Barbara Billard, along with archivist Barry Raphael, all of whom were part of the Tanners' collective. Lumonics Immersed is meant to be a healing experience, in which the Tanners' light sculptures pulsate to soothing music by Marc Billard. The $20 immersive happens every Saturday from 8 to 10:30 p.m., and provides a mind-expanding, unforgettable experience.
