Chilean bands have always given us something to talk about with their participation at Baja Prog (Tryo, Exsimio, Subterra). With Ergo Sum surely this tradition will be reasured due to the fact that their electro-acustic proposal (in which they mix the energy of progressive rock with the use of vibraphone, flute and african percussions), will delight a demanding audience. The characteristics of their music are: feeling, identity, spirituality, complex compositions and an exceptional technique. Without a doubt this band will surprise with their original proposal.
