Some context: Thor Heyerdahl (Norwegian pronunciation: [tu:r 'haei@da:l]; October 6, 1914 - April 18, 2002) was a Norwegian adventurer and ethnographer with a background in zoology, botany, and geography. He became notable for his Kon-Tiki expedition in 1947, in which he sailed 8,000 km (5,000 mi) across the Pacific Ocean in a hand-built raft from South America to the Tuamotu Islands. The expedition was designed to demonstrate that ancient people could have made long sea voyages, creating contacts between separate cultures. This was linked to a diffusionist model of cultural development.
In 1955-1956, Heyerdahl organized the Norwegian Archaeological Expedition to Rapa Nui (Easter Island). The expedition's scientific staff included Arne Skjolsvold, Carlyle Smith, Edwin Ferdon, Gonzalo Figueroa and William Mulloy. Heyerdahl and the professional archaeologists who travelled with him spent several months on Rapa Nui investigating several important archaeological sites. Highlights of the project include experiments in the carving, transport and erection of the notable moai, as well as excavations at such prominent sites as Orongo and Poike. The expedition published two large volumes of scientific reports (Reports of the Norwegian Archaeological Expedition to Easter Island and the East Pacific) and Heyerdahl later added a third (The Art of Easter Island). Heyerdahl's popular book on the subject, Aku-Aku was another international best-seller.  In Easter Island: The Mystery Solved (Random House, 1989), Heyerdahl offered a more detailed theory of the island's history. Based on native testimony and archaeological research, he claimed the island was originally colonized by Hanau eepe ("Long Ears"), from South America, and that Polynesian Hanau momoko ("Short Ears") arrived only in the mid-16th century; they may have come independently or perhaps were imported as workers. According to Heyerdahl, something happened between Admiral Roggeveen's discovery of the island in 1722 and James Cook's visit in 1774; while Roggeveen encountered white, Indian, and Polynesian people living in relative harmony and prosperity, Cook encountered a much smaller population consisting mainly of Polynesians and living in privation.  Heyerdahl notes the oral tradition of an uprising of "Short Ears" against the ruling "Long Ears". The "Long Ears" dug a defensive moat on the eastern end of the island and filled it with kindling. During the uprising, Heyerdahl claimed, the "Long Ears" ignited their moat and retreated behind it, but the "Short Ears" found a way around it, came up from behind, and pushed all but two of the "Long Ears" into the fire. This moat was found by the Norwegian expedition and it was partly cut down into the rock. Layers of fire were revealed but no fragments of bodies.  As for the origin of the people of Easter Island, DNA tests have shown a connection to South America, critics conjecture that this was a result of recent events, but whether this is inherited from a person coming in later times is hard to know. If the story that (almost) all Long Ears were killed in a civil war is true, as the islanders story goes, it would be expected that the statue-building South American bloodline would have been nearly utterly destroyed, leaving for the most part the invading Polynesian bloodline.
How well did his theory go over?
A: According to Heyerdahl, something happened between Admiral Roggeveen's discovery of the island in 1722
Some context: Morbid Angel is an American death metal band based in Tampa, Florida formed in 1983 by guitarist and sole remaining original member Trey Azagthoth, vocalist and bassist Dallas Ward, and drummer Mike Browning. Widely considered as one of the most influential bands in the genre and important in the transition of death metal from its thrash metal roots, they were one of the first bands to incorporate guttural vocals, up-tempo blast beats, multiple tempo changes and dark atmosphere. They have been described as one of "the most influential and emulated bands in death metal", alongside Obituary and Cannibal Corpse, and have been cited as an influence by many later bands. They were also the first death metal band to experience mainstream success in connection with being signed to Giant Records in 1992, heavy rotation of their music videos on MTV, and having the music video for the song "God of Emptiness" shown on an episode of Beavis and Butt-head.
1991 saw the release of their second album, Blessed Are the Sick, which was met with widespread critical acclaim, and is considered by many to be a landmark release in the death metal genre. The album differed from its predecessor, showcasing a more "sludgy" side to the band. Following the success of Altars of Madness' and 'Blessed are the Sick', in the Spring of 1992 Morbid Angel were signed by Irving Azoff to Giant Records for one album, with the option of five more. Later that same year, second guitarist Richard Brunelle was kicked out of the band due to alleged substance abuse.  On June 22, 1993 the band released their third full-length album 'Covenant', which went on to sell over 150,000 copies in the United States alone. Their record label dedicated promotional resources to the album, and commissioned music videos for the songs 'Rapture' and 'God of Emptiness'. These music videos were put on heavy rotation by MTV, and the latter also appeared on the television show Beavis and Butt-head. The success of the album enabled the band to tour with Black Sabbath and Motorhead across the United States from February through March of 1994, which David Vincent credits with helping the band significantly expand their audience.  The band released its fourth studio album, Domination, on May 9, 1995, which featured new guitarist Erik Rutan of Ripping Corpse. It proved to be a somewhat controversial album among fans, featuring a slower, more atmospheric and experimental sound than on previous albums. Music critic describes the album's sound as "more groove-oriented". The album has gone on to sell over 100,000 copies in the United States alone. Regardless, following the release of the album their record label dropped them from their roster.
Did they have any singles between 1991-1995?
