Released in 1988,
Leprosy is considered to be ahead of its time musically, and a groundbreaking achievement in the genre. According to Eduardo Rivadavia of
Loudwire, the album made it apparent that the
death metal genre was "already advancing by leaps and bounds." Jonathan Horsley of
Guitar World wrote, "There is an argument to be said that, of all the great death metal bands, Death were the least heavy. [But,] if
Leprosy is not the heaviest death metal guitar album, it’s possibly the gnarliest, worthy of Ed Repka’s career-best cover art, and essential listening." In a poll by the German
Rock Hard magazine,
Leprosy was voted the number one of the 25 most important death metal albums of all time. On April 29, 2014, a three-disc remastered edition containing bonus tracks was released via
Relapse Records. The title track was covered by the
blackened death metal band
Akercocke on their 2007 album
Antichrist. Dutch
melodic death metal band
Callenish Circle covered "Pull the Plug" as a bonus on their
Flesh Power Dominion album, released in 2002; shortly thereafter, Norwegian band
Zyklon also recorded "Pull the Plug" to be used as a bonus track. Finnish
thrash metal band
Mokoma covered the track "Open Casket", with lyrics in Finnish and titled "Avoin Hauta", on their
EP Viides Vuodenaika. "Pull the Plug" was also covered by American band
Revocation. The album cover is featured in ''
Metal: A Headbanger's Journey''. In 2013, author
Ian Christe wrote: "Now, twenty-five years and twenty-five thousand death metal bands later,
Leprosy sounds almost normal. The essence of these cries has echoed with a tormented dimension all along. As you breathe the rotten scent, try not to go insane with awe that Death's early brilliant depravity could change the world so completely.
Leprosy proved that this death metal shit was
for real, and today it has become inescapable." In 2024, Joe DiVita of Loudwire named the album's cover artwork as one of the "31 Scariest Metal Album Covers of All Time". ==Track listing==
