Larvae of Caddis fly Hydropsyche instabilis are typical dwellers of fast flowing streams, where they spin nets to filter drifting food material from the water. After spending 1 – 2 years in water Caddis fly metamorphosis for pupal stage which lasts for some 2 weeks. After those weeks pupa crawls on to the coastal weeds and metamorphose for adult flying specimen which lives for about a month. During life time in water they need high oxygen saturation and therefore as well are indicators of good water quality.
Hydropsyche instabilis in translation means “Instable soul of the water” and perfectly reflects the concept of the Nature Concert Hall aiming to unite science, poetry and music to reveal different aspects of Nature in our life.
Water is essential and self understandable part of our life. Nevertheless, as it is recorded by European Environmental Agency, each fifth waterbody in Europe cant cope with everyday hyman needs and only most resistent aquatic dwellers can live there. Eutrophication and sedimentation processes are important as well for waters in Latvia. Due to excess nutrients rivers and lakes are overgrowing with water plants. Sediments brought from the catchment are clogging rivers. About 100 000 beavers are worsening situation by building dams and creating local flooding risks.

I tell you! If all events were like this one, I'd have to fire most of my staff! After more than 5,000 people spent hours in the sand dunes - not one piece of garbage left behind! Almost no disruption of the surroundings!
Thank you for creating such an amazing, wondrously beautiful, true and gratifying art! May you have enough creativity for many more years
The Oss year's concert is of special significance to me personally as after the Ogre concert, under the dome of stars - I asked my then-girlfriend to be my wife!
Once I was stopped in a shopping mall by a couple. They complained that under the influence of our event, their son was asking for a microscope - not latest toy - for Christmas.
Thanks to all musicians and people who can create something with such synchronicity of the soul, science, meditation and other emotions!
