Coachella will be streaming again this year on YouTube.
There is no streaming schedule yet. Even the event schedule is usually posted only a day or two before it begins.
But Underworld is likely to be playing the Sahara Tent again, and there is a dedicated Sahara channel on YouTube. So we’re likely to get an UW stream at least one of the weekends.
