CURSE UPON IRON is undoubtedly one of the better known works in Estonian choral music. Already in it's original form, it contains all the primary characteristics of this particular project: shamanic chants, rhymes borrowed from Kalevala, the primeval power of runo-singing. To this we add some increasingly popular ethno-rockers and the 54 trained voices of the Grammy Awarded only full-time professional male choir in the world. The works of the world-renowned composer emeritus Veljo Tormis and those of Metsatöll are manipulated without prejudice by Tauno Aints, whose background is revealed by the names of his bands - Speculative Rokenroll Band and Genialisted. However, the young man also has a cum laude in the field of composition, so both sides of the music are treated equally and are fused into a whole. Metsatöll becomes grand choral music, Veljo Tormis turns into rock.
