*Edition Of 100 Hand-Numbered Copies* Obras Portuenses da Década de 20 is a project developed by Sonoscopia for Cultura em Expansão, a Porto City Council programme that seeks to decentralise and diversify the city's cultural offer. Since 2021, four commissions have been made each year to composers from Porto, or with a strong connection to the city, who portray their vision and listening to the city in a unique way. Given the territorial specificities of Cultura em Expansão, each composer is assigned one of the programme's areas of intervention - Bouça, Pasteleira, Miragaia and Campanhã. The works are worked on in close collaboration with the Supernova Ensemble, a group chosen for this project because of the participatory way its members give themselves to each piece. We feel and listen to the city today in order to think about tomorrow.
