Jeff Parker & ETA IVtet Happy Today - Led by guitarist Jeff Parker, featuring saxophonist Josh Johnson, bassist Anna Butterss, anddrummer Jay Bellerose, the ETA IVtet is a band that grew out of a weekly residency started byParker in 2016 at Northeast Los Angeles venue ETA. Over seven years of holding down that residency, Parker's ETA ensemble evolved from a bandthat played mostly standards into a group known for it's transcendent, long-form (sometimesstretching out for 45 minutes or more) journeys into innovative, often uncharted territories ofgroove-oriented, painterly, polyrhythmic, minimalist and mantric improvised music.
