SOFA is proud to announce the release of Spektralmaskin [Spectral Machine], a collaboration by the Norwegian experimental musicians Jo David Meyer Lysne and Peder Simonsen. This capacious, shimmering record owes its title to a sort of prospecting: the process of sliding e-bows—small magnetic motors of adjustable speeds used to sustain strings, here of Lysne’s own design—along guitar strings to produce harmonics.
