Antonio Caban Vale (1942 - )
Antonio Cabán Vale [note 1] a.k.a. "El Topo" (born November 22, 1942) is a guitarist, singer and composer of Puerto Rican folkloric themes. He is one of the founders of the "new song" movement (Spanish: nueva canción) of the early 1970s. His danza Verde Luz (Green Light) became a popular symbol of national dignity, to the point that it is viewed by many as almost a second national anthem, and has been interpreted by international singers.
