REKA is a rare sonic experience including numerous performers : six extraordinary soloists of rare ancient vocal traditions - from a Tibetan Böhn Lama to the Tenores guttural singing of Sardinia, two virtuoso percussionists playing a complex set of numerous gongs and the insides of a concert piano; a huge vocal “Crowd” formed by a heterogeneous group of participants with no need of previous musical knowledge - composed of the residents of the city in which the concerts take place, guided by coded gestures of the conductor and a “user friendly” graphic & verbal score. All these, coordinated simultaneously on the scene by two conductors.
