Petr Vrba and Veronika Mayer use non-idiomatic improvisation to research the combination of textural materials, crossing them with vibrations of objects on the speakers, pure sound waves, feedbacks, tones coming from trumpet, accordion, electronics, and laptop, culminating in the creation of a muscular frenetic soup of tense energy fields.

Petr Vrba explores non-idiomatic improvisation using trumpets, clarinets, vibrating speakers and other electronics which made him one of the most active experimental musicians in Prague. He works with a lot of projects like Prague Improvisation Orchestra, Poisonous Frequencies, NOIZ, Doppeltrio, Rouilleux and Junk & The Beast.

Veronika Mayer is a composer, musician and sound artist from Vienna. Pure sounds, natural given phenomena and material are the basis for her work, always emphasizing hardly perceptible elements, giving it a reduced but essential form and very clear structures, following the characteristics and inner behaviour of the sound itself. In her electronic performances and instrumental works she explores the continuous evolvement and expansion of single grains of sound. Focusing on the striking results of very smooth and minimal changes in sound manipulation, she observes the slightest differences and variations during these processes of manipulation.
