With Escalator Fest in limbo, Lo-Fi owner Scott Behrens decided to thrust Octopus Fest 2 into that void, giving Seattle psychedelic-music fiends reason to rejoice. (Disclosure: I’m DJing part of the event with Explorateur.) American luminaries Lumerians and Moon Duo bring interstellar vibes and Suicide/Hawkwind mantras, respectively, while locals Brain Fruit, Hair and Space Museum, This Blinding Light, Rose Windows, and The The The Thunder trigger endorphin rushes through analog-synth wizardry and kaleidoscopic rock explorations.
