If you like modular synth sounds and repetitive grooves and techno- and I do- then you might find something to enjoy in this collaboration between Carl Craig and Klauss, an Argentinian electro-acoustic ensemble who have been making music in Buenos Aires since the 1980s. Two tracks have been released on Planet E, Carl Craig’s legendary Detroit electronic label. Momentum runs to over 12 minutes, a looped synth part setting it going and staying there throughout as the tension builds, some oscillation and a big kick drum. Momentum was the result of an improvised jam and in some ways it sounds like it- but there’s plenty to enjoy here, in the sounds and the loops and propulsion.
