"Las Ánimas del Cuarto Oscuro" is one of the most enigmatic Mexican projects of the 80s, because with the only album they released at the end of the decade they achieved a cult status. Toño Sánchez Uribe on vocals and synthesizers; Juan Ezcurdia on guitar and José Ezcurdia on bass, managed to bring together the experiences of eight years playing separately to form a style of rock with substance and release a full-length album without having to attract the attention of businessmen, promoters, record labels and other paraphernalia.
