Illud Divinum Insanus

Illud Divinum Insanus is the band's only album featuring Norwegian guitarist Destructhor, the first with bassist/vocalist David Vincent since Domination (1995), and the first to not include longtime drummer Pete Sandoval, who had undergone back surgery when recording began.[2] Former Hate Eternal drummer Tim Yeung recorded the drum tracks for this album.[2]

Illud Divinum Insanus took more than five years to materialize. Work on the album began in 2006, and it was originally going to be released in 2007, but was pushed back several times while the band continued touring and writing new material. After four years of writing, Morbid Angel began development on the album from June 2010[2] to January 2011 at several studios, including Mana Recording Studios and Red Room Studios for the drum recording, and D.O.W. Studios for the bass, guitars, and vocals. Illud Divinum Insanus was mixed in Hollywood, California, with Sean Beavan.

"Nevermore" single cover.

The cover art for the album was unveiled on March 30, 2011. It was designed by Brazilian artist Gustavo Sazes, who commented:

To create this cover we worked from several references, ideas, elements, and I would say a 'world' of options and paths. After a long brainstorming period and some [good and bad] ideas left behind, we came up with the concept of this organic surreal insane being; a fallen God or a weird mirror image of our own madness. It is a different Morbid Angel cover for sure, but I think that's how Morbid Angel is...Deviant and different on each new release. They never repeat themselves. They are always pushing the boundaries and setting new standards. I'm really proud of the final results and hope the fans appreciate my work, while listening to the new album![3]

The album's track listing and information of various release formats were unveiled on April 5, 2011.[4] Prior to the release of the album, a single for the song "Nevermore" was made available on May 16 as a digital download and on 7" vinyl. The cover artwork for the single was designed by French artists Valnoir and Fursy Teyssier for Metastazis.[3] The single also contains an exclusive version of the song "Destructos vs. the Earth", remixed by Combichrist.

Of all the remixes I've been asked to do I never expected one of the world's most notorious death metal bands to have an interest in hearing their music on the dance floor. However, "Destructos" is one of those tracks that are so versatile that it could have been recorded as a folk song and it would still sound amazing. I'm honored to be a part of this project and am excited to see how the Morbid Angel fans react to this unusual new direction.

In 2012, a double remix album called Illud Divinum Insanus – The Remixes was released.

The album received mixed reviews from critics and generated a strong backlash from fans, many of whom were dissatisfied with the group's attempt to add an industrial element to the album.[11] Louisville Music News labeled the album a "failed experiment" and a "joke", and described Illud Divinum Insanus as Morbid Angel's St. Anger, in reference to the Metallica album.[13] Metal Injection gave the album 3/10 and described the album as "a joke" and an "overall bummer to listen to."[14] They criticised the lack of heavy, interesting guitarwork and Pete Sandoval's absence from the album, writing that "Instead, we’re left with fifty-six plodding minutes of (mostly) forgettable death metal and/or offensively terrible industrial metal." They also highlighted David Vincent's lyrics for particular criticism, describing them as "atrocious" and "pretty awful pretty much the entire time". Blabbermouth criticised the album, particularly for the programmed drums, and argued that even the four best tracks on the album sounded "uninspired and even if the band dumped blood, sweat and tears into these songs, that still wouldn't make up for the fact that a track like "Radikult" takes up space on the same album."[15]

Conversely, Phil Freeman of Allmusic said that while "those who love the band's earliest records...are bound to see Illud Divinum Insanus' experiments with industrial...as betrayals of everything the group once stood for", "many of the songs on Illud...are as raw and savage as anything the band's ever recorded", and that the album is "a left turn by a band that's already made many of them throughout its...career".[6] Metal Hammer gave 9/10, describing the album as "a twisted, confrontational masterpiece".[11] The album received praise before its release from artists including Mikael Åkerfeldt from Opeth, Anders Nyström from Katatonia and several other metal artists.[16] However, drummer Pete Sandoval disliked the album, saying, "I don't know why they did that with the DJs, they could've have [sic] just done a separate project without calling it a Morbid Angel album. That might have been better."[17] Sandoval was unable to contribute to the recording of Illud Divinum Insanus due to injuries, and later left the band entirely.[18]

Guitarist Trey Azagthoth calls the album "a confused effort", whose unfocused direction ultimately led to David Vincent's departure in 2015, and offers no apologies over the computerized beats and effects, with a comment about the song "Radikult", calling it "a silly song", "...I had nothing to do with that thing."[19]
