"Portal Tombs" is a terrifying but electrifying exploration of the gloomy depths of human nature: a monolithic manifestation of the musical force that is Mass Worship. Drawing inspiration from bands such as At The Gates, Mastodon and Meshuggah, Mass Worship could be likened to many bands, but somehow forge their musical identity into something exceptionally distinctive and transcendent, and with enough confidence and conviction to win over even the most orthodox fans of the genre.
