Krallice seems incapable of not releasing new material for more than a year or so at this point. The band released the Ygg hurr album in 2015, the Hyperion EP and Prelapsarian album in 2016, and Go Be Forgotten and their collaboration with Neurosis' Dave Edwardson titled Loüm in 2017.
While the details are still unclear, Krallice has expectedly announced they're hitting the studio soon for a new release (or maybe releases?) pretty soon. Given it's just about November, I'd venture to say the record will be out in 2019, but who knows – Krallice does all their own recording.
