Morbid Visions is the debut album by Brazilian thrash metal band Sepultura, released in 1986 through Cogumelo Records. While later albums have a more political edge, Morbid Visions (along with the Bestial Devastation EP) is notable for "Satanic" themes. The band said many lyrics were fashioned after those of Venom and Celtic Frost, as they could not write in English at this point. As late as 1987, Max Cavalera was still translating his lyrics word-for-word, as evidenced by the demo "The Past Reborns the Storms".
The production of the album is rather poor. In the liner notes of Roadrunner's reissue of the album (which includes the tracks from the EP Bestial Devastation), Cavalera admits that the band neglected to tune their guitars during the sessions. The original vinyl pressings of Morbid Visions featured the first movement of Carl Orff's Carmina Burana ("O Fortuna") as an unnamed introduction. This composition was left off the CD re-release, probably because of copyright issues. This would mark the last appearance of the group's original lead guitarist Jairo T.
