Orbital are the first act confirmed for this year's Sonar festival.
The recently reformed duo, made up of brothers Phil and Paul Hartnoll, have promised that they won't be playing any new tracks, just the big hits which includes 'Chime', 'The Box' and 'Belfast'.
Sonar is Spain's annual progressive music and arts festival which runs for three-days showcasing cutting-edge technology, interactive exhibitions and emerging music.
During the day there is over 300 activities including concerts, films, installations and DJ sets before the event morphs into a Mediterranean Mecca for clubbers with a selection of DJs, VJs and shows that explore all of dance music's connotations across four simultaneous stages.
Sonar 2009 will take place at Sonar, Barcelona in Spain from 18-20 June.
Tickets are already on sale priced at €125 for a three-day pass.
