Cellist Khabat Abas and violist Ivor Kallin engage in a taut, exploratory duo dialogue built from extended techniques, fractured vocalizations, and deliberate use of space, where cantankerous textures, unconventional pacing, and carefully placed silences shape a curiously absorbing improvisation that balances raw intensity with focused restraint.

"Tapsalteerie, a Scots word, describes the upside down world we inhabit, and our response to this chaos is depicted in an echo of rage."-Confront
This duo recording brings together London-based cellist Khabat Abas and Scottish violist Ivor Kallin in a sparse, abrasive, and often deliberately unsettled exchange that thrives on friction, restraint, and unpredictability. Drawing heavily on extended techniques, both musicians stretch their instruments beyond conventional roles, with Abas introducing objects and unstable textures on the cello while Kallin folds fractured vocalizations into his viola work, creating a sound world that feels simultaneously confrontational and inquisitive.
The music unfolds with unusual pacing, favouring space, hesitation, and sudden shifts in density over linear development, allowing small gestures to carry disproportionate weight. At times cantankerous and resistant, the duo's interaction rewards close listening as details surface gradually, revealing a careful balance between raw impulse and collective awareness. The title's reference to tapsalteerie - a Scots term for an upside-down or chaotic state - resonates throughout the performance, as the duo navigates a volatile sonic landscape that mirrors disorientation without collapsing into noise.
