A crossover with the St.Giga thread, check out what I just found:
An autotranslated description from an old Japanese blog:
Do you know St.GIGA? It is a broadcasting station that once did digital music broadcasting using the empty channel band of BS 5ch.
At first, there was no timetable, and I liked the fact that they played a combination of natural sounds and music according to the tide, and there was almost no talking.
For a while after the station opened, terrestrial Fuji Television ran a 25-minute program of natural scenery and music created in collaboration with St.GIGA in the late-night slot. This is " Quiet Mode ".
The vibes here are immaculate. Just a lot of cool footage of dolphins swimming and playing while excellent 90’s house music plays. I’d love to find more of this show.
