Its been 40-years since Ken Kesey and The Merry Pranksters turned Timothy Leary’s famed slogan, tune in, turn on, drop out, into a form of art. And, on Halloween, the Pranksters will celebrate the 40th anniversary of the first acid test with a multi-media party at Las Vegas The Beach. In addition to the Furthur Bus & The Merry Band of Pranksters, a number of well known entertainers will be on hand including The Mutaytor Bassnectar with special guest Michael Kang, The New Riders of the Purple Sage, Mikio DJ Haj, Spunn Trusty, Flow Motion and the Everyone Orchestra. While many in attendance will no doubt be providing their own visuals, Optical Delusion and Smoke & Mirrors will enhance the evenings experience. The event will run from 6 pm until dawn, beginning with a seminar discussing the impacts of the Merry Prankster Acid Tests on art and culture. Among the other attractions fans should expect: Snakedancers, Stage Magicians, Circus Acts and more.
