TENGGER's official YouTube channel has published a live performance of "Spiritual", a track from the duo's eighth album SKY (Guruguru Brain, released 10 July 2026). Itta and Marqido — the Korean-Hungarian pair from Seoul — build it from harmonium, voice, toy instruments and analogue synths into slow, luminous drone. Echo Mandala presents this as a curated archive selection, not a new release: the original performance date is not specified. It joins the SKY full-album video and the official clips for "Blue" and "High" already in the archive.
