TAU is a new ensemble formed by three internationally acclaimed musicians in the fields of improvised and experimental music. Their collaboration gives rise to a polyphonic, organic body of sound – interwoven with energetic tensions, ruptures, and unexpected abysses. Emerging is an acoustic space of intensive alertness, resonance, and perception.
Tiziana Bertoncini oscillates between contemporary composition, improvisation, and electroacoustic music. Trained as a violinist and visual artist, her interdisciplinary practice spans from sound-space installations to music theatre. She is a member of Ensemble ]h[iatus and has performed at institutions such as ZKM, WDR3, and Horizons Sancy.
Angelika Sheridan explores the flute’s sonic possibilities beyond classical conventions. With extended and self-developed techniques, she shapes contemporary and improvised music. She performs with groups such as Ensemble]h[iatus, the Multiple Joyce Orchestra, and the collective Impakt. She also teaches at the Cologne University of Music and Dance.
Ute Wassermann is a vocal artist, composer, and performer. Her voice shifts between electronics, creaturely sounds, and sound sculpture – expanded through objects, whistles, and acoustic costumes. She composes for international festivals and ensembles, including MaerzMusik, Transart, and Musik der Jahrhunderte.

The duo – the most intimate form of improvisation – enables musicians to respond to one another in a depth unmatched by any other constellation. Every second demands to be heard, understood and immediately transformed into sound.
Julie Sassoon and Willi Kellers achieve this with great sensitivity, subtlety, and emotional nuance, but also with ecstatic cascades of sound.
Lyrical melodies meet percussive eruptions, layered with drumming rhythms reminiscent of Bartók or Stravinsky.
These elements alternate with jazz-inflected passages, shamaic sound meditations, and almost inaudible atmospheric textures. The result is a highly dynamic sonic universe – intense, fragile, and utterly unpredictable.
Trained as a classical concert pianist, Julie Sassoon found her way to free improvisation through jazz. In 2009, she moved from London to Berlin and gained regular presence on the city's experimental music scene, performing with many musicians also presented by Offene Ohren e.V. in Munich, such as Tom Arthurs, Yorgos Dimitriadis, Miles Perkin and Paul Schwingenschlögl. Her German-Jewish roots became the subject of a deeply personal musical exploration on a solo album.
In 2011, Willi Kellerss performed at the opening concert of MUG together with bassist Christoph Winckel and legendary British trombonist Alan Tomlinson.
Peter Brötzmann, Ruf der Heimat and Boom Box are just a few pillars of his extensive musical work. He has played with countless major figures in jazz and improvised music – including Keith Tippett and Marilyn Crispell.
Julie Sassoon is their equal in terms of sheer emotional intensity.
In 2017, Julie Sassoon & Willi Kellers captivated the audiences with their first appearance together at MUG. Now, after eight years, this exceptional duo returns for a second concert – promising emotional depth, musical freedom, and masterful interplay.
This concert is made possible also by the Federal Culture Prize Applaus, which Offene Ohren e.V. was awarded in autumn 2024.

Simon Camatta (1976) is an internationally recognised improvisation and jazz drummer. He studied jazz at the Folkwang University of the Arts in Essen. Based in Essen, and is curating the JOE Festival 2025 at Zeche Carl (6–8 February 2026).
Simon Camatta breaks with conventional formats, creating evening-length improvised solo drum concerts and interdisciplinary work at unconventional venues. He performs in theatres, collaborates with independent dance companies and visual artists – for instance, in his project "Drums Meet Canvas". His album "This is not a Solo Record" features guest musicians and field recordings.
Having collaborated across the full spectrum of contemporary musical styles with a dazzling range of artists, Simon Camatta distills the essence of these experiences into a percussive, virtuoso performance on this evening.
ErikM (alias Erik Matt) is a French sound artist, electroacoustic composer and visual artist. For over thirty years, he has been developing an interdisciplinary practice that joins sound design, visual art, performance, and installation. His work, deeply rooted in an expanded ecology of sound, explores the subtle relationships between matter, perception, environment, and disruption.
Situated at the intersection of visual and audio art, his oeuvre spans electroacoustic performance, phonography, immersive installations, as well as acousmatic and radiophonic works. Whether manipulating raw sonic material or capturing the unheard elements of the living world, ErikM creates shifting, critical and intuitive listening environments – permeated by contemporary themes such as technological transformation, catastrophe, intimacy, and shared space.
In his project Idiosyncrasy, ErikM presents an electroacoustic performance that draws its sound sources in real time from freely accessible internet streams. The focus here is no longer on the stored sample, as in traditional musique concrète, but on the immediate, the accidental, the open.
This real-time organisation of sonic material connects the here and now with the distant world beyond the horizon. A fictitious cartography unfolds by means of these flowing, open sounds, drawing the listener into an abstract sonic world.
