“After The Speakers split in 1969, Humberto Monroy co-founded Siglo cero with Jaime Rodriguez, Mario Renee, Ferdie Fernández and Speaker’s drummer Roberto Fiorilli. Siglo cero was a progressive rock outfit, with major jazz influences. In 1970 they released Festival de la Vida, which was recorded live the 27th of June of the same year at a performance in Bogotá’s Parque Nacional, before 10,000 people.”
