Sonar is a music and digital art festival held in the heart of the city of Barcelona for three days every June.
At last year's festival, more than 80 thousand people enjoyed a musical line-up that combined major names in today's electronica with ideas for minority interests.
Sonar is a meeting point both for an audience from all over the world eager for new ideas, and for professionals, who find that the festival atmosphere is the ideal place to display their products and make contacts.
This year the festival will take place on 18, 19 and 20 June.
