What is techno if not a powerful conduit for energy? The movement of a sequence, the surge of an effects rush, the respondent reaction in every individual dancer and the moving mass of the crowd as a whole. Whether the frequencies transmit directly into the brain through the intimacy of a headphone reverie, reverberate through the architecture of a space or fill the formless void of the open air, techno’s potency to initiate and stimulate energetic events is profound. This is something Pfirter understands intimately, having spent more than 15 years exploring ways of manipulating the energy on a dancefloor. Of course, energy is not just about volume and aggression. Tonality, spatial processing and composition can have just as profound an effect as the thump of the kick drum. On his new album Altered States, Pfirter proves that point by zeroing in on the cerebral, psychedelic elements of his craft across 10 incisive tracks. The Argentine producer consciously approached his second album (following 2019’s The Empty Space) with a minimal mindset, using a very focused set of drum machines and synths to achieve a consistency across the record. Captured over a short burst of creativity, it’s the sound of an artist pushing a limited array of tools as far as possible. Despite this concise palette, it’s not an album that repeats itself, but rather an extended trip that flows from one detailed, textured immersion to the next. The dense, febrile waves of hard-oscillating ripples in ‘A Future In Chaos’ and the sparkling, off-key chimes adorning ‘Yearn’ all speak to Pfirter’s gift for extravagant, surrealist expression within his tracks. ‘Altered States’, by way of contrast, succeeds in its absolute immediacy – a piledriving statement of bleep-driven intent.
