Born in Tehran in late 2013 under the visionary initiative of guitarist Ehsan Sadigh, Quartet Diminished emerged not merely as a band, but as a living acoustic laboratory. From their foundational recordings in “Station One” to their cross-continental evolution, the ensemble has meticulously deconstructed and rebuilt the boundaries of genre—blending complex polyrhythms, intricate microtonal structures, and collective improvisation. Their journey from the intimate studios of Tehran and Istanbul to landmark global collaborations with legendary artists like Tony Levin and Markus Reuter on “Deerand” stands as a testament to uncompromising artistic curiosity and sonic evolution.
