[8] MEAT MACHINE is noted for creatively combining a wide range of disparate styles and influences,[9][10] its clear and aggressive production[11][12] and the creation of cinematic atmospheres with disturbing undertones.

[7][13] Regarding the combination of ambiance and violence, Sophie Maugan from Metal Hammer wrote that "the songs are equally immersive and destined to enthrall anyone with a penchant for altered states and arse-shattering riffs".

[6] It is also the first time that the band uses female vocals, sung by guitarist Eaten Roll I, in contrast with Rider G Omega's death growls.

[13][23] But the trait that was most often brought into focus was its eclecticism[1][7] – while most reviewers found the mix of styles to be bold and enticing,[9][11] others thought it to be incoherent and confusing.

[24][25] In this respect, Langdon Hickman from Consequence of Sound wrote that "Obsidian Kingdom are a band that feels like they can syncretistically alloy anything under the sun".
