It's only been a month since this year's Coachella ended, but the Indio, California festival has already unveiled dates for 2013 on its official website, along with advance sale info. Coachella 2013 is set for April 12th-14th and April 19th-21st.
Starting this Thursday (May 17th) at 10:00 p.m. PT, advance passes will go on sale for exactly a week, ending the following Thursday at 10:00 p.m. PT. The festival's website points out this advance sale will be the only opportunity to utilize the Coachella Purchase Plan. The website also lists a new price system for 2013, saying "The price you see is what you pay – prices reflect all fees included." General ticket sales will be available early next year.
