Elio Varesse is an ambient composer from Spain. He has put out a lot of free albums on Bandcamp.

His music is described in series as:

BLUE – Brilliant. Luminous. Radiant. Shining. Refulgent. Effulgent. Open Spaces.

GREEN – Serene. Peaceful. Cool. Placid. Gentle. Quiet. Tranquil. Partly Cloudy.

BROWN – Melancholic. Wistful. Gloomy. Rainy. Very Cloudy. Somber. Moody. Weeping. Sorrowful.

WHITE – Flutes, Sine Waves and Birds.

But all of them comprise short (<10 minute) tracks with the feeling of a symphonic tone poem.
