They achieved great success in their country, and became Revelation Rock band in various media in 1995. In 1996 the current line-up was established. The same year, they began recording the Opera Rock CD "Jesus de Chamberi", produced by Alberto Plaza and Mago de Oz. The CD was edited in 1996, with the company's new name "Locomotive Music".
