Mostra Sonora is an international festival of contemporary music created in 2005 in the town of Sueca (Valencia). Since then, it is celebrated each spring, and uninterruptedly, in this Valencian town.

Over the years, Mostra Sonora has become a referential framework for performers and composers, as well as an essential event not only for the most orthodox listeners of the new avant-garde proposals but also for an audience interested in experiencing new listening proposals through current sound art.
