Ingeborg Freytag comes from a family of musicians and received extensive training in instrumental, vocal, and improvisational music, encompassing classical, jazz, and global music. As a multi-talented musician, singer, and sound artist, she moves within genre-crossing spaces between artistic practice, cultural education, and digital and analog formats. She draws on constantly renewed and expanded sources of experience and roots in neoclassical music, jazz, global influences, urban rituals, and a contemporary musical sensibility that recognizes and playfully interprets—or consciously subverts—traditions, boundaries, and rules.

Her innovative performance practice of free improvisation and spontaneous composition is uniquely suited to capturing current events, moods, and snapshots of moments and transforming them into artistic experiences. Rural and urban lifeworlds, people's social relationships, and archaic and artificial forms of societal expression are captured, transformed, and rendered into sounds and (sound) images by Ingeborg Freytag as an artistic challenge, a philosophical undercurrent, and a creative impulse. The result is the creation of site-specific music, inspired by the presence of the audience and firmly anchored in time.

Benjamin Stache, a musician, grew up near Leipzig in a house full of quirky sound machines. For him, the absurd has always been normal. From a young age, he made music with marble zithers, rotary dial telephones, MIDI switches, and much more. He also received violin lessons. In 2002, he joined the newly formed ensemble Atonor (then AG Klangexperimente) at his school, which specialized in the diverse instruments of the ensemble's founder, his father, Erwin Stache. From 2008 onwards, the group evolved from a school setting into an independent ensemble, which he then led. Simultaneously, he began studying Sinology in Leipzig and completed his studies in Berlin. He continuously composes new pieces for the ensemble, which performs throughout Europe. In addition, he is artistically active in the field of cultural education. In workshops, Benjamin Stache introduces children and young people to what he himself experienced from a young age.
