The mostly-metal & stoner rock Las Vegas festival that has expanded in recent times to include adjacent bands like Beach House and Mogwai on the lineup, will return to Mandalay Bay casino in August 2020 for another multi-stage, three day festival (Aug 14-16) preceeded by the one stage Psycho Swim pool party (Aug 13). Psycho Las Vegas tickets are on sale now, and the initial lineup is here!

That's Ty Segall, Mayhem, Blonde Redhead, Ulver, Windhand, Kaelan Mikla, and Mephistofeles. That's already exciting, but more acts to be announced in December.

For Ulver, this is the first sign of a return to the States since the cancellation of their west coast dates earlier this year. For Mayhem, this is yet another date in what is already a big 2019 and 2020 for them.
