Between man and machine: new KAU album explores the beauty of the unpredictable

Posted on 09/10/2025

'Unknown Waveforms' is the new album from Belgian trio KAU, out today via Sdban Ultra. Marking an evolution since their 2023 release 'The Cycle Repeats', this new record captures a more personal, immediate, and unfiltered version of the band’s sound. In an increasingly digital world, KAU takes a different route, with an album rooted in human connection, live energy, and creative spontaneity. Here, the trio reflect their take on instrumental music, drawing heavily from jazzhip hop, and electronic influences.

At the heart of 'Unknown Waveforms' lies the starting point of three musicians in a room, writing and composing music on the spot. For KAU, this idea mirrors their working method: long jam sessions, free-flowing experimentation, and shared moments of inspiration. Songs often take shape slowly, unfolding over hours or days, but always built collaboratively as a trio.

KAU kept overdubs to a minimumavoided excessive editing, and prioritized spontaneous choices over calculated ones. In a time when the future of live, improvised music feels uncertain, they double down on the physical, the real, and the immediate. The album resists the pristine polish of modern production, favoring the warmth and imperfection of analog synthesis. The band embraces the character of their instruments, particularly vintage gear, where subtle flaws add beauty, depth, and personality.

'Unknown Waveforms' is out today via Sdban Ultra, available on all streaming platforms & vinyl.
