"11 Micro-Exercises were invented by Christian Wolff in response to a commission from the Miniaturist Ensemble. For Wandelweiser Editions, other miniaturists perform these eleven pieces (plus two bonus pieces): Beat Keller and Reza Khot. Keller and Khot are two electric guitarists who pierce the ivory (sometimes tear it) and respect the principle of a musical art free from preconceptions. Nine seconds, twenty-two, one minute and thirteen, or eleven minutes and forty-seven… The length of these exercises is irrelevant; what matters is their eclecticism. Played with the thumb or attacked boldly, the guitars are concealed, modest, impatient, irritated… They can ignore each other or phrase together; in other words, they form a couple whose daily life is thankfully unpredictable, anything but ordinary."
