Arne Deforce has always been attracted to new musical models, linked to a sense of wonder for changing the inner state of mind and revolutionizing our musical consciousness. 

He is known for his passionate and unparalleled performances of contemporary and experimental music. His inventive programs explore new forms of musical expression where the discovery of the cello's "otherness" and uninhibited creative listening are paramount. His approach and playing background is inspired by modern art, philosophy, nature and astrophysics. More recently, Arne Deforce has been fascinated by exploring a new aesthetic of performance practice with concert programs that seek to make us more aware and critically sensitive to the great ecological mutation and digital revolutions. How these challenge and redefine our identity and our relationship to non-human life forms, nature and the digital. In other words, art and music as the practice of a new experiential aesthetic in the sense of developing and increasing our sensitivity to changing perspectives.

As a musician and researcher, he is passionate by how new concepts and relationships in music can be developed at the intersection of music, art, science and technology between the instrument, the musical gesture and the use of electronics. In particular, by the possibilities of sound processing and the expansion of sound possibilities through the highly developed use of advanced surround live electronics. Inspired by this, his explorative playing technique took the endless variations of a cello's strings and the use of the bow as a kind of hard ware sound processor, to another level of praxis.

His collaboration on Richard Barrett's ‘life-form’ (2012), a full-length cycle inspired by biodiversity and electronic life forms, or Raphaël Cendo's short and powerful apocalyptic piece Foris (2012), for example, demonstrates that with the physicality of playing and the pervasive use of electronics, a whole new spectrum and range of musical possibilities can be developed.

In 2017, Arne Deforce joined forces with composer Hèctor Parra and sound designer Thomas Goepfer to push the boundaries of their ability and knowledge. The starting point was a shared interest in astrophysics, specifically gravitational waves and black holes and the question of how to create a new kind of cosmology in music, following Stockhausen's idea as creating "a flow of superconscious cosmic electricity transformed into sound." The final score resulted in an extraordinarily compelling sonorous cosmic firework based on an imaginary psycho-acoustic journey through a black hole; a full-length journey of cosmic music through the infinite multidimensional time-spaces of sound.
