As Kevin Bronson reported last month, Prince has now been officially added to the Coachella lineup. He'll headline Saturday. Last month Aphex Twins, Redd Kross, Adele, Serj Tankian and Goldfrapp were also added to the lineup. For the first time ever, Amtrak will be running a Coachella Express train from Union Station and to the Empire Polo Fields. It's free, and only available to campers.
