A lot of the time Mossenmark's artistry focuses on our public places, everyday sounds and the sounding things that surround us everyday. Working in public spaces and using them as arenas for artistic expression is a way of exploring venues and stages distinct from those that are traditional and defined as such. Public space is a place for free expression, a place where the city acts as the citizens' own veranda or patio and the square is the stage and space for manifestations, demonstrations or, quite simply, free speech. Public space is a venue where political, social and economic power structures operate together and society becomes visible. It is here that the observer and listener can focus on the social and sonic structures existing in these environments and create concentrations of these ongoing processes.

As a sound and performance artist with over 35 years' experience of working in public space, Mossenmark has found that one question in particular is the essential driving force behind his explorative interactions: what does it mean, artistically, to recognise and respect the democratic right of people to have access to art in what we call public space? He has succeeded in reaching out to a general audience, beyond the traditional music and culture audiences. For him an important, and indeed central, goal is to invite – and communicate with – an audience that has no special knowledge, and in this way try to break down the borders and hierarchies.

Mossenmark is today full professor at the Academy of Music and Drama, Göteborg University, Sweden. Between 2009–2023 he was artistic director of the festival GAS – Gothenburg Art Sounds and since 2007 has been one of the founder members of Verona Risuona, a festival in which art, music and performance take place in the streets and public spaces of Verona, Italy.
