Morbid Visions is the debut studio album by Brazilian heavy metal band Sepultura, released on November 10, 1986, by 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 (note the similarity of the album title to Morbid Tales).
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. They were only starting to learn English at this point, so they had to translate the lyrics word-for-word using a dictionary. All pre-1992 releases 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 due to copyright issues.[citation needed] This would mark the last appearance of the group's original lead guitarist Jairo Guedz.
