Synth pop outfit Crystal Castles from Toronto have unveiled a video for their frenetic new track Concrete. The duo of Ethan Kath and Edith Frances have announced a run of European and North American live dates. And, yes!, you’re safe! Luxembourg’s den Atelier is among them! Having played only a small handful of shows in the past two years, the date presents an opportunity to experience new songs from Crystal Castles’ much anticipated forthcoming 4th album, the follow up to 2012’s critically acclaimed III.
