January 2nd, 2023. Aside from being the second of a new year, it was a pretty ordinary night at ETA in Los Angeles, where guitarist Jeff Parker - alongside his ETA IVtet with saxophonist Josh Johnson, bassist Anna Butterss, and drummer Jay Bellerose - had been holding down a regular Monday gig since 2016. At the time, nobody knew it was the first gig of the last year that ETA would be open for business.

Over seven years of holding down that residency, Parker’s ETA ensemble evolved from a band that played mostly standards into a group known for its transcendent, long-form (sometimes stretching out for 45 minutes or more) journeys into innovative, often uncharted territories of groove-oriented, painterly, polyrhythmic, minimalist and mantric improvised music.

With that musical growth, the crowds for Parker and his band at ETA grew across the years too. What started as a sparse gathering of weeknight drinkers, friends, family, and Chicago expats (coming to get a shot of nostalgia for the atmospheres Parker used to create at Rodan across the ‘00s and early ‘10s) grew into a Los Angeles nightlife staple with a packed house and a line of down the block for every show.
