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.
