His compositions, which waver between contemporary classical music and contemporary improvised music, paired with expressive stage presence, have made this musician/composer a distinctive representative of a young Austrian music scene, which is characterised by its interest in musical crossovers and co-operations with musicians of other genres.


Here is how Bertl Müller himself describes his music, "All my artistic projects have one thing in common; they actually do not merely compare to absolute musical standards and goals only; less and much more than that. It is about the "co-operation" of different genres of artistic expression and to make states noticeable beyond familiar processes: large-scale, formal arches with hidden references and bridges built into the microstructures."

Description of Style

What is a composing improviser, improvising composer, real-time composer? Bound improvisation? Following a motif, circle around it, even right down to the beastly level. Do not ask the desk, ask the instruments, listen to them. Collect and harvest; observing the grown architecture, leaving the inner proportions completely to the moment of creation. It is one of the circle's characteristics that at 180° the position of 0° is one hundred percent wrong. Or is both possible at the same time? To circle around a centre, which burns us once we reach it, yet keeps us alive at the right distance. My tools are the trombone, voice, sometimes live-electronics and many small instruments. Though, this does not mean anything with respect to content. Nevertheless, I want to take myself to this orbit. As a soloist, I like to refer to the tradition produced by the tension between composition and improvisation. The only tradition I have at least the chance to somehow authentically understand, is the one I was born into. Nevertheless, I welcome influence from the outside and therefore incorporate foreign elements in my art. However, my ancestors weren't cotton pickers in the Confederate States, nor were they Siberian shamans; therefore I am only an observer of these traditions. My main instrument, the trombone, possesses a classical-romantic repertoire which can hardly be taken seriously; a true advantage, as other people's fear of masterpieces written for the trombone stemming from their former training is alien to me. Thus, I can lean back and watch pieces concerning me - improvisational and enriched with my own material - passing by during the concert performance. If you sing alone in your bathtub you can hear the orchestra, you do not need an instrument; my tub is on the stage, a highly intimate process.
