If you have half a chance to spend three days on an Austin, Texas ranch listening to psychedelic rock bands, you should probably do that because that sounds amazing. The organizers of the Austin Psych Fest have announced this year’s lineup, and though every act on the bill can certainly be called “psychedelic” in one way or another, the definitions of the term range from twinkly sha-la-la retro-rock to stoner doom churn to synth gloop. The Brian Jonestown Massacre and the Dandy Warhols — the two bands whose rivalry inspired the 2004 documentary Dig! — will both headline, as will Loop, the reunited British masters of bleary infinite-repeat minimalism. Panda Bear is on the bill, as is his Animal Collective bandmate Avey Tare, with his new band Slasher Flicks. (I would not bank on an impromptu Animal Collective set, though I suppose stranger things have happened.) The rest of the bill is loaded, and it includes the Horrors, the Zombies, the Black Angels, the War On Drugs, of Montreal, Liars, Black Lips, Unknown Mortal Orchestra, Oneohtrix Point Never, Graveyard, Woods, Mono, Temples, Dead Meadow, Mikal Cronin, Peaking Lights, Pink Mountaintops, the Fresh & Onlys, Acid Mothers Temple, Yamantaka // Sonic Titan, Mark McGuire, Destruction Unit, Pure X, Tunde Adebimpe’s Higgins Waterproof Black Magic Band, and the excellently named King Gizzard & The Wizard Lizard. More artists will be announced, and I hope Young Thug is one of them. It all goes down 5/2-4 at Carson Creek Ranch.
