Taking the trombone into unusual territory, Danish composer and trombonist Maria Bertel, a member of Fire! Orchestra and Jooklo Danish Group, uses amplification to emphasize unusual and sometimes aberrant aspects of the bone, each of ten solo pieces focusing on various aspects of sound, noise, alien utterance and drone that she coaxes out of the instrument.

"Actions For Free Jazz Orchestra" was originally written by Polish composer Krzysztof Penderecki for the New Eternal Rhythm Orchestra, assembled by Don Cherry for the occasion and conducted by composer himself; this new extended reading and conduction of the score from 2018 was originated and directed by Mats Gustafsson, a powerful update and expansion of the original work.
