Officially billed as”a festival of Advanced Music and Multimedia Art,” the three-day Sónar Music Festival has been taking place in Barcelona every year since 1994. Last year, it branched out to events in New York and Washington, D.C., and this year, it’s coming to Millennium Park and the Chicago Cultural Center just across Michigan Avenue on Sept. 9 to 11.

Performers at the fest, which was announced today, include Kid Koala’s “scratch-rock” project the Slew, electronica legends Oval, Martyn, Lesley Flanigan, Ben Frost, Nosaj Thing, Nicolas Bernier + Martin Messier: La Chambre des Machines, and Jimmy Edgar, as well as the Catalan artists Bradien, bRUNA, Huan, and Faraón. According to the press release:

The objective is to take the philosophy of the Barcelona festival to the North American city, with all the features that have made Sónar an international touchstone: with an ambitious and high quality line-up featuring plenty of electronic experimentation and its derivations and unusual venues of the highest calibre, in this case the Jay Pritzker Pavilion – designed by Frank Ghery – in the popular Millennium Park (the 9th of September) and the famous Chicago Cultural Center (the 10th and 11th of September).

The festival is collaborating with Adventures in Modern Music, the five-day festival sponsored by the British magazine The Wire and the Empty Bottle. Acts announced for that fest so far include guitar noise guru Rhys Chatham, (Chicago Museum of Contemporary Art, Sept. 8), stoner-rock gods Sleep (Logan Square Auditorium, Sept. 9), and Efterklang (the Empty Bottle, Sept. 10).
