Shaddah Tuum is a collaboration between Nicolas Lefort and Brandon Rosenbluth alternately known as niko 'shaddah' lfo and xorzyzt. Shaddah Tuum began in 2013 as a natural outgrowth of their developing facility with computer production tools and listening habits leaning towards the current electronic industrial-dance resurgence most prominently promoted by labels Blackest Ever Black, Downwards, Hospital Productions, PAN, Subtext, and Opal Tapes.

Employing avant-garde compositional techniques such as serial sequences, micro-tonal melodies, sample-based production, synthetic vocal manipulation, feedback loops generated by sound sources including guitar, percussion, voice, no input mixer, spring reverb, field recordings, and processed through a complex array of digital effects and generative modules, the duo aims to recreate their music live on stage reconnecting physicality to abstract sound and leaving space for in-the-moment channeling of volatile creative impulses.
