AKKU Quintet are a Swiss band based in Berne, from where they dispense a minimalistic jazz groove to great effect. Between the mesmeric ostinato, subtly shifting grooves, resonant overtones, tingling harmonics and languorous, yearning melodies, AKKU Quintet hover somewhere between smouldering, jazz-infused intimacy, expansive post-rock vistas and an insistent minimalist intensity.  Following their acclaimed 2015 album, Molecules, AKKU Quintet have released their third record, Aeon. Intense, brooding and powerful, it contains a sequence of darkly beautiful compositions. The band avoids any obvious soloing. Instead they move through their tunes in a highly disciplined, tight formation which fans of Sonar and the work of zen-funk pioneer, Zurich-based pianist, Nik Bärtsch, will recongise and respect.
