"Even Hell has Its Heroes by director Clyde Petersen is an impressive work, given its ambitious mission: to portray the mysterious music of the Earths by bringing together, on a journey, those who contributed to it. A poetic and, as it should be, humanised portrait of a work driven by introspection, experimentation and contemplation. In it we are (always) carried away by the guitars, in the presence of the landscapes of a strange and familiar America. As fascinating and distant as the work of Earth that this beautiful documentary has so well unveiled to us."
