Natural Information Society — the ensemble led by Joshua Abrams that’s established itself as “a driving force in Chicago’s vibrant jazz, post-rock, indie, and creative music scene” (NPR Music) — announces Perseverance Flow, a new album due out October 24 via eremite Records (North America), Aguirre Records (EU), and New Soil Music (streaming).

After a trilogy of double LPs by expanded manifestations of the band that began in 2018 with Mandatory Reality and continued through Since Time Is Gravity (a Pitchfork Best Jazz & Experimental Album of the Year selection & MOJO’s #1 Underground Album of 2023), NIS returns to its core formation of Lisa Alvarado on harmonium, Mikel Patrick Avery on drums, Jason Stein on bass clarinet, & composer/multi-instrumentalist Joshua Abrams on guimbri for one continuous 37-minute composition across a single LP.
