The two Canadian outfits have pooled their resources into one festival, taking place in May and June.
Both festivals will be celebrating their 15th anniversaries in 2014. Traditionally they've been two separate events, but this year they'll co-host a six-day affair called EM15. Organisers say more than 100 Canadian and international acts will perform at venues across Montréal, including the festival's HQ at the city's Museum of Contemporary Art.
The first wave of announcements includes several North American debuts, including Dinos Chapman's Luftbobler A/V show, Robert Henke's Lumière performance and dub techno artist Fluxion. There will be Canadian debuts for Voices From The Lake (AKA Donato Dozzy and Neel) and Matthew Dear's new Audion live show. They will be joined by Archie Pelago, Heatsick, Nicolas Jaar, Magic Mountain High and Shackleton, with more names to be added soon.
