Daring experimentalists Nels Cline and Yuka Honda present an exclusive two-night Walker collaboration. Perhaps best known for their ensemble work—Cline with indie rock band Wilco and Honda with ’90s art-pop duo Cibo Matto—they innovate continually as solo artists. For River Mouth, Unseen Green, they bring a stacked lineup of friends and collaborators for a one-of-a-kind musical blowout.

On Thursday night, Cline is joined by leading musicians, including guitar virtuoso Julian Lage, vocalist Shara Nova (My Brightest Diamond), drummer Glenn Kotche, and more. Rotating through varied configurations, they produce a kaleidoscope of sounds and textures, spanning punk, jazz, electronica, and pop.

On Friday night, producer and multi-instrumentalist Honda presents a two-part performance dedicated to longtime friend and collaborator Yoko Ono. Accompanied by a full band, Honda performs excerpts from her and Glenn Kaino’s forthcoming I Am Yoko opera. She also invites notable collaborators, including Theo Bleckmann and Jason Lindner, onstage to perform an improvised live score to Ono and John Lennon’s 1970 avant-garde film Fly.
