To me “Atsuko Chiba” sounds like a Japanese band name, but no. According to their bio at Spotify they are from Montreal (Canada?). That is irrelevant. What is relevant is that I am enjoying their music. As usual, I am no good with labels.

Oddly, this album remembers me Diego Trip (see https://arturmarques.com/wp/2019/07/07/listening-to-diego-trip-al-espacio/): the same blend of old and new, less lyrics, less predictable.
