Easily the band that maximizes the full potential of music videos, OK Go is doing a unique performance at Royce Hall on Saturday. They will be live scoring/playing to those innovative music videos. There will also be time in the program for Q&A from the audience. Perhaps the secrets behind the making of “The One Moment,” “This Too Shall Pass” and “I Won’t Let You Down” will be revealed. If symphony orchestras can play live to movies, why can’t a rock band play to their own videos?
