Azusa is a progressive extreme metal supergroup that originated in 2018 as a project between cousins and former Extol members, Christer Espevoll and David Husvik. The two had been demoing material, when then The Dillinger Escape Plan bassist Liam Wilson expressed admiration for Extol. The three added on pop vocalist Eleni Zafiriadou of Sea + Air, and the band recorded their debut album, Heavy Yoke. The band is currently signed with Solid State Records.
