What do we actually hear of the landscape in which we live? The drone of cars, revving scooters, and rumbling trams. Shop doorbells, church bells, ringtones, and singing birds. Heels tapping on the pavement, children's voices in the school, and cows in the countryside... We hear them, but rarely listen.

With 11th-century liturgy and experimental music, ordinary sounds and electronic noise, soundtracks of sharks, web DJs, speech karaoke, radio, and voices, Marres opens a world of sound that will have Maastricht buzzing this summer. In Marres, works are presented by Haroon Mirza, Ryan Gander, Sarah van Sonsbeeck, Lyndsey Housden, Chaim van Luit, Joseph Beuys, Anri Sala, Nishiko, and Paul Devens.

Outside Marres, Kaffe Matthews composes an audio-visual installation inspired by sharks for the marl caves of Sint Pietersberg. In the cells of the Minderbroedersberg, Espen Sommer Eide surrounds the visitor with scattered sounds of political unrest. In the crypt of the Basilica of St. Servatius, the ensemble Graindelavoix develops from July 16 onwards a sound installation based on the holy Servaas liturgy. Rutger Zuydervelt and Mark Bain make work for the Marres ice cellar and the 18th century fortifications. At Intro in situ, works by Thomas Rutgers, Jitske Blom, and David Helbich can be heard.

The composition of Graindelavoix will not be presented before July 16, because the music collective holds open rehearsals between 16 and 22 July in the crypt of the Sint Servaas Basilica. The concert is on 22 July. As of 24 July, the sound installation can be heard in the church. During this period, Graindelavoix will also give brief appearances, performances, and a lecture-performance at Marres.
