[5] On 29 November 2019, the band released the lead single of their upcoming album titled "The Grey (VIXI)" and its corresponding music video.

[7] On 20 March, presumably due to the ongoing COVID-19 pandemic concerns, the band announced that they delayed the release of the album to 3 July in a bid to help them properly promote it.

AllMusic gave the album a positive review saying, "While hardly an updated recipe – strident, gravel-gargling verses that yield soaring clean choruses – it's a dish that the band have perfected over the years, and Cannibal is the finest representation of that sound to date.

"[10] Distorted Sound scored the album 7 out of 10 and said: "If you're going into Cannibal already hesitant that the Southampton crew often can't resist overdoing their blend of vocal styles – you'll find little respite on this record.

"[12] Hunter Hewgley from KillYourStereo gave the album 55 out of 100 and said: "While FAR from perfect, Cannibal shows that Bury Tomorrow are aware of their strengths and are playing to them well.

I find myself somewhere in that hard to distinguish middle: content and admiring the clear potential that Bury Tomorrow display but also not having it 'wow' me at all.

While I know that Bury Tomorrow's fanbase will adore Cannibal, I can't help but see it for what it is: a flawed, familiar-sounding melodic metalcore album, with a couple good songs spread out amongst the larger track list.

"[13] Louder Sound gave the album a very positive review and stated: "The sheer talent and artistic wisdom it takes to produce such a towering, jam-packed record nearly 15 years down the line proves why Bury Tomorrow are still such a formidable force in the metalcore realm today.

"[14] Rock 'N' Load praised the album saying, "Bury Tomorrow have set their own bar exceptionally high with this record, it has been very well put together, each track standing out and not a filler in sight.

They've poured blood, sweat, tears, passion and so much more into this, the music matching the emotion in the vocals is something they've managed to execute well and it makes for a fantastic listen.
