Celebrating 27 years as a recording artist Massif Trophies is the first solo release for Editions Mego. In 2015 he set off on a month long hiking trip in Gran Paradiso to explore the acoustic environments in the alpine landscape. Drawn to the monotonous and physical effort that mountains and high altitudes contributes, this became one of the main inspirations for the album, reflecting upon the perception of the landscape during several hours of physical difficulty, let alone rapid weather changes, horizontal thunderstorms and rock avalanches. It is also about the scope of details and perception of the path and the myth of the mountain as the accursed or sacred place.

The five pieces contains narratives based on experiences and recordings from the trip.
