The threads of our past never unravel, they hover like invisible webs, occasionally glistening due to a sly angle of the sun. On 'Multi-Love,' Unknown Mortal Orchestra frontman and multi-instrumentalist Ruban Nielson reflects on relationships: airy, humid longing, loss, the geometry of desire that occurs when three people align. Where Nielson addressed the pain of being alone on II, Multi-Love takes on the complications of being together.

'Multi-Love' adds dimensions to the band's already kaleidoscopic approach, with Nielson exploring a newfound appreciation for synthesizers. The new songs channel the spirit of psych innovators without ignoring the last 40 years of music, forming a flowing, cohesive whole that reflects restless creativity. Cosmic escapes and disco rhythms speak to developing new vocabulary, while Nielson's vocals reach powerful new heights.

"It felt good to be rebelling against the typical view of what an artists is today, a curator," he says. "It's more about being someone who makes things happen in concrete ways. Building old synthesizers and bringing them back to life, creating sounds that aren't quite like anyone else's. I think that's much more subversive."

While legions of artists show fidelity to the roots of psychedelia, Unknown Mortal Orchestra shares the rare quality that makes the genre's touchstones so vital: constant exploration.
