After some brief investigation, I agree that this band meets the required notability. In particular, Infant Annihilator's The Elysian Grandeval Galeriarch reached #22 on Billboard's "Top Rock Albums" during the week of August 20, 2016.[1][2]

Comment: Previous attempts at creating this page were rejected due to a lack of notability. The band has since charted on several charts for their second album and gained a lot of attention/notoriety in the metal and deathcore communities, making them notable per WP:NMUSIC/WP:BAND.
Also, if this page is accepted—due to the nature of its content—it might be a target for vandalism, and a good candidate for semi-protection. — Tha†emoover†here (talk) 17:49, 7 May 2018 (UTC)
Comment: Per WP:NMUSIC, a band is notable if it Has had a single or album on any country's national music chart. Their second album charted so it seems notable to me.
However, I do understand the concern and annoyance of editors who have had to create-protect the article. Bkissin (talk) 21:06, 20 April 2018 (UTC)
