ARS artificial intelligence will create music and video based on the presence of users and the interactions they generate during the eight-minute walk along the corridor. Everybody will become a musical note that forms part of changing patterns of sounds, visuals and light beats along the inside of the corridor, generating a constantly evolving audiovisual atmosphere.

The project includes a space for performing live music, where members of the Barcelona Metro Buskers Association (AMUC) will be able to play on the ARS STAGE with excellent sound conditions and a chance to boost their performances through the visual technology implemented in the connecting corridor at the station.

This was the winning project in the challenger to improve user experience in the interchange between lines L3 and L4 through music, launched by Barcelona City Council and Transports Metropolitans de Barcelona (TMB), through Fundació BIT Hàbitat  and in conjunction with the Fundació Barcelona Music Lab.

The pilot project will only be installed in a specific section of the corridor, with a trial conducted beforehand in a controlled environment to ensure the rules on universal accessibility. The project will get 50,000 euros in funding, covering roughly 80% of the cost, plus a prize of 3,000 euros.

ARS GRÀCIA is a project by ARTIFICIA, a Catalan platform for the promotion and dissemination of artificial intelligence in the arts, with the support of the Institute for Research into Artificial Intelligence (IIIA-CSIC), Kreomúsica and the Barcelona Metro Buskers Association (AMUC).

Two other projects each won prizes of 3,000 euros: Atmósferas en Tránsito, by the agency we are Labels.team, and El Cànon de Barcelona, by the team Flop Work.
