Concerns Music is a Spanish label run by Kalter Ende, a techno artist who’s used the label to release his own flavour of sharp, intelligent techno. The label has released some EPs to success so far, including Kalter Ende’s own. Concerns Music is characteristically metallic. It is even at times, understated. The label’s upcoming first full length sees his name alongside Developer, Stanislav Tolkachev and more contemporary techno heavyweights.
