Returning to Samurai Music following last year's Between Veils, Sciama opens up a new portal of exacting sonic exploration with Wave Interaction. Moving through dense drone shrouds, steely sound design and tense, taut rhythms, Michael Watters lays out a manifesto for waveform resonance within the half-time D&B tempo range. Wave Interaction is the precursor to a forthcoming album that will lay out a purposeful study of the interaction between machine-made sound waves and human perception, inspired by the teachings of early electronic music pioneer Daphne Oram. As an opening statement, 'Cele' maximises on a patient, spacious arrangement that allows the carefully sculpted layers of waveforms to resonate with minimal distractions. Far from minimal, it's a dense and evocative sound world Watters builds up. 'Excitation' brings more detailed percussive sequencing into the mix, teasing pin-prick snatches of breakbeats and designer ripples that dart around the psychoactive tonal elements in the mix. 'Intermodulaton I' opens the second half of Wave Interaction on a crisp, stepping beat more than ready for the club. As ever, functionality is only one part of the picture as further uncanny sheets of ambiguously tuned synth work unfurl across the austere framework. 'Shifting Formants' has a knottier, tunnelling quality that joins the dots with techno hypnotism, made all the more immersive by the harmonic overtones radiating off the vibrant lead lines that give the track its distinctive character. Guided by a clear intention and a finely honed studio practice, the return of Sciama hails an impactful addition to his considerable catalogue and tees up further compelling exploration on the impending long player.
