Acid Witch hasn't released a new album since 2012's Witchtanic Hellucinations, though the band always releases albums in October. So basically you just needed to keep an eye out about once per year and hope that that year was the year.
2017 happened to be "the year," as Acid Witch has dropped its new album Evil Sound Screamers. The best way I can describe the album is "Halloween doom," because it's pretty much everything I love about bands like Dopethrone and Electric Wizard, though with a ton of Halloween-ey sound effects and lyrics.
