With the first weekend of the 2013 edition of the Coachella Festival two days away, the organizers have not only posted the set-times for April 12-14, but have announced that Coachella will again be streamed via their YouTube channel. You can check out graphics detailing each area on Page 2; hopefully you're able to catch all of the acts without too much in terms of conflicts.
UPDATE Pigeons & Planes has posted the webcast set-times.
