OUT.FEST is Barreiro's international exploratory music festival, running since 2004 across the industrial town just south of Lisbon on the Tagus estuary. Rather than street art, the festival centers on experimental and improvised music, staged inside repurposed spaces such as old churches, municipal libraries, decommissioned warehouses and local social clubs.
Barreiro rarely makes it onto a Lisbon visitor's itinerary.

FEST is not a mural or street-art festival, it is Barreiro's exploratory music festival, running annually since 2004 and now well past its twentieth edition
