Bastarda has been played on NTS in shows including The Early Bird Show w/ Jack Rollo, featured first on 1 September 2019. Songs played include Letaniae Mortuorum Discordantes, Vita In Ligno Moritur and Predulcis Eurus.

Founded by clarinettist, improviser and composer Paweł Szamburski in conjunction with two other unconventional musicians: Tomasz Pokrzywiński (cello) and Michał Górczyński (contrabass clarinet). This unusual combination of instruments creates a unique, completely new timbre, which has become the characteristic feature of Bastarda’s style.
