In september 2018 , I put my body in action for five consecutive weeks, throught a 860 km walk on the "Camino del Norte » in Spain. « River on the way » originated from recording a river I met during my walk, between Asturias and Galicias regions, close to « El silencio » beach. I instrumentalise the rhythm of this river from the recorderings of its various streams music (density and texture) , to querry the frontier metaphorically as a connected boundary.
