LCD Soundsystem and Air for Sónar
James Murphy is back for a second year running, after performing a disco-only DJ set with LCD cohort Pat Mahoney in 2009.
French act Air will also perform live, after making a triumphant return to form with their Love 2 album in 2009.
The 2010 festival (June 17-19) will be take place simultaneously in Barcelona and A Coruña, the first time in its history that it has been held in two locations.
The A Coruña event, dubbed Sónar Galicia, will have a Sónar by Day with a music line-up, and a multimedia and audiovisual area with a special emphasis on Galician artists. The Sónar by Night stages will feature the latest leading lights in electronica.
