Dhidalah is a Tokyo-based psychedelic rock trio associated with the Guruguru Brain label and the wider Japanese krautrock and space-rock scene. Their debut full-length Threshold (発端, 2019) grew out of the group's weekly jam sessions, combining doom weight with motorik repetition and spacious textures. This archive upload presents the album in full, track by track. Echo Mandala has not heard the recording; the selection rests on the band's established scene presence and the album's reputation among Japanese psych listeners. It is offered as context for the Japanese psychedelic continuum, not as a new-release announcement. The video links to YouTube and is not hosted here.
