Chaos Butterfly began in 2005 with Jonathan Segel and Dina Emerson, making mostly-improvised electro-acoustic music using computers, instruments, voice and wine glasses. (See in albums below: "threelivingthings" and "Radio")

A number of guests joined in, including saxophonist Biggi Vinkeloe and cellist/guitarist Helena Espvall and shakuhachi player Kiku Day. (See: "Live at Studio Fabriken", "Unforeseen Events").​

​

Jonathan moved to Sweden in 2012 and the band (as such) disappeared while Jonathan continued making similar sounds by himself (See: "Summerleaf", "Artificial Relics", "Echopraxia", "Superposition of States" "Current Motion" and "Downstream Motion") More recently, however, adding in other players brought back the idea and name of Chaos Butterfly. Newer collaborations include "Trapped Light" with percussionist Andreas Axelsson—also from Sista Maj— and "Folded Space" with bassist Hasse Horrigmoe. 

​

2025 sees a new large-scale piece, "Hall of Mirrors", based on Halldorophone improvisations done at the Stockholm Elektron Musik Studios, with several other instruments overlayed including violin and guitar, plus Daniel Borgegård Älgå on flute and bass clarinet + electronics, Andreas Axelsson on drums and percussion and Tom Djll on trumpet + electronics. 

​

And continuing with Daniel Älgå, adding Karen Jacobson, in a plan concocted during Great Learning Orchestra recording at Atlantis studios in Stockholm for an upcoming piece by Christina Campanella, Chaos Butterfly re-emerged for a show at Larry's Corner on May 9, playing with Jair-Rohm Parker Wells (on the bill, as well as literally. He did a solo set, then became a chaotic butterfly. I believe this show was recorded.)
