Remember back in the 70s when the cool thing was to watch Wizard of Oz while listening to Dark Side of the Moon and smoking pot? Me, neither. In case you missed it, you can read up on the synchronicity of the experience on Wikipedia.
Then you can watch the movie while listening to the album. (Not sure how long it will be availble since both the movie and the album are copyrighted material.)
