Freelektron was founded in 2016, and the band has performed in several events, clubs and festivals around Finland also under the name Jimi Tenor & Ilmari Heikinheimo Duo. In its music the band combines jazz and the possibilities of electronic music, leaning heavily on improvisation. The band's sound is larger than its actual size due the drums trigger system.

The band released its live-recorded debut album Freelektron via the record label Jazzaggression in spring 2020.
