El Peyote Asesino is a Uruguayan rock band formed in 1994 in the Villa Española neighborhood. It is made up of Fernando Santullo -credited as "L. Mental"- and Carlos Casacuberta on vocals, Daniel Benia on bass, Juan Campodónico on guitar, Bruno Tortorella on keyboards, Matías Rada on guitar and Pepe Canedo on drums. His style combines heavy metal, funk, and rap, something that was atypical in the Uruguayan rock scene at that time.
They made their debut in 1995, with the release of their self-titled album El Peyote Asesino, produced by Gabriel Casacuberta -Carlos' brother. This album had a good impact in the Montevidean underground movement, where it sold 1,000 copies, being the best-selling Uruguayan rock album during the first months of 1996.
In September 1997 they began recording their second LP at Can Am studios in Los Angeles. Terraja, was released on 31 August 1998 under the Universal Music Group label. Apart from maintaining the rap metal style of his predecessor, Terraja experiments with multiple genres such as electronic music, soul, milonga, candombe and tango. The most popular song on the album is "Mal de la Cabeza."
