Cloud Study: “Rivers of Light”

Описание: The highlight of this video is the music of Latvian composer Eriks Esenvalds in his "Rivers of Light" piece for chorus (see the lyrics at the end of this description, which are mostly in English). I'm sure that it’s really about the Northern Lights creating their amazing streams of colors and shapes. But I can’t see them in Chula Vista, which is where the clouds were recorded.
Performer: Portland State University Chamber Choir conducted by Ethan Sperry. NAXOS. 8.579008.
Lyrics:
Kuovsakasah reukarih tåkko teki, sira ria
Tåkko teki
Sira ria, sira siraa ria

Winter night, the sky is filled with symphony of light, the sky is flooded with rivers of light. The doors of heaven have been opened tonight.

Guovssat, guovssat radni go, libai libai libaida
Ruoná gákti, nu nu nu

From horizon to horizon misty dragons swim through the sky, green curtains billow and swirl, fast-moving, sky-filling, the tissues of gossamer. Nothing can be heard.

Light shakes over the vault of heaven, its veil of glittering silver changing now to yellow, now to green, now to red. It spreads in restless change, into waving, into many-folded bands of silver. It shimmers in tongues of flame, over the very zenith it shoots a bright ray up until the whole melts away as a sigh of departing soul in the moonlight, leaving a glow in the sky like the dying embers of a great fire.
