Cerulean Blue (Fluttering Shadows).
My video, not my music (hope this is obvious - it's a Roger & Brian Eno track from their Mixing Colours LP), though the track has been processed very slightly, using Soundtoys Microshift, and Soundtoys Primal Tap. The latter is a software interpretation of Eventides Prime Time 93 delay unit, and was controlled manually using a control surface.
Please give it a thumbs up if you like!
