During the exhibition TRIGG at Art Centre of Gävle in 2007 Mossenmark took a part together with artist Jörgen Svensson with the sounds and video piece "Harry and Hugo".

The sound of the scream of a young woman coming through an elder mans mouth, a cry that investigates mens desire to scream.

A cry which today might feel like a sign that indicates danger, a cry for help, exposure, who can scream, show anxiety, exposure, fear, seen through male/female perspective.

The piece could be heard by a sound installation in the city centre, where a scream could be heard at every even hour during the afternoon and evening everyday.
