OUT.FEST - Barreiro International Festival of Exploratory Music, on the south shore of the Tejo, at Barreiro, is considered to be one of the most important experimental music events in the country.
From improvised music to Abstract Electronics, from free Jazz to Noise, without forgetting Contemporary Classical and the languages revealed to the world each passing day, not yet with ratified classification, such are the many stands that give OUT.FEST.
