Sierra Sam and Marcus Vector have been friends for about five years, and during that time have established three record labels, released numerous tracks, thrown parties, and played throughout Europe with their live and DJ sets. Belgium's Sierra Sam is also closely tied to the Detroit techno community, having spent extensive time there and co-producing with Suburban Knight of Underground Resistance. He has also released two EPs in collaboration with Bloody Mary, one for ToysForBoys and one for Einmaleins. He also holds down a quarterly residency at Berlin's Tresor. French-born, Brussells-based Marcus Vector first established himself as a DJ but has more recently focused on the production side of things, often collaborating with Lust Addict, including tracks for Lesizmore's digital imprint Playground.
Despite all this activity, the Jump Rope EP marks the first release these guys have produced as a duo. The title track begins with a propulsive skitter, and soon a dark but catchy melody looms into the foreground. Static noises snap, crackle, and pop and fill the room with aural haze. "Hop Scotch" is even darker, with a recurring distorted growl taking over the low end of the audio spectrum, complementing the busy locusts that are swarming within the high end. "Four Square" closes the EP, easily the deepest, most hypnotic track here, with jittery percussive elements that get marinated in reverb.
