Houses of Worship is the collaborative project of thisquietarmy and Hellenica. The duo released their first album as Thisquietarmy x Hellenica entitled "Houses of Worship" on Somewherecold records in 2021. In 2023 the duo decided to go under the name of the first album and released "Migration": A soundtrack and film on Midira records and toured Europe in April 2023. After spending the winter months before the tour converting public payphones into playable instruments, their sound installation "Les cabines télésymphoniques" was presented at the 39th edition of Festival International Musique Actuelle Victoriaville. "....this is a magnificently atmospheric work that goes beyond dark ambience and ventures into the vastly cinematic, space-drifting expansiveness that transports the listener beyond the terrestrial domain." - Aural Agravation. "...On n'est pas loin non plus du métal, de la musique industrielle, avec des paysages électroniques marqués par les drones de guitare. C'est une musique lourde, puissante, volontiers hypnotique, aimant les atmosphères saturées, enflammées." - Inactuelles Musiques Singulières
