Portal is an Australian extreme metal band whose style is an unorthodox fusion of death metal, black metal, dark ambient and experimental music. The band's hybrid musical style is characterised by heavily distorted guitar riffs, down-tuned rhythms, and vocals ranging from "menacing, echoing" sound effects to death grunts.
Writing for Popmatters, Adrien Begrand noted that "death metal always pretends to be scary, but [...] it's all rather harmless. That said, however, I make no mistake in saying that the death metal peddled by Australia's Portal is truly friggin' terrifying". Lead guitarist Horror Illogium has described Portal's intent as "to capture a cinematic horror scope". They have released seven full-length albums to date, as well as a number of EPs and split releases. Their most recent albums, Avow and Hagbulbia, were released in 2021 on Profound Lore Records.
