The new art work Puiden itku ( The Cry of the Trees) is in process and  will mix existing research data and long-term time series with real-time data flow, and be combined and composed with the sound of the emissions, originated from VOC (volatile organic compounds) emissions during the act of thinning the forest. Forest ecologist Anna Lintunen (INAR) has been supporting the artists to find ways to sonificate trees: the earlier works by the Band composed by Kalle Hamm, Hermanni Keko, Olli Aarni and Lauri Ainala feature soft stemmed plants using a sound recording method developed by Soviet botanist Ivan Gunar.  Check out the earlier works of Band of Weeds here.
 
The Cry of the Trees resonates with the Rune 44 called Koivun itku (The Cry of a Birch Tree) from Kalevala, Finnish epic story from 1835. In the poem a birch tree laments the way how people treat trees using them as a mere resource.
