The Coachella lineup for 2020 has been announced. I don't really know how ticketing works anymore but it looks like you can register for weekend 2 passes. Weekend 1 is "sold out". If you're thinking about it, I would just wait to get tickets as weekend two passes seem to have been dumped the past couple years. Either way, Coachella takes place the weekend of April 10-12 and April 17-19, 2020. General passes start at $429.
