It appears that Jack Owen is no longer a part of the Deicide line-up. There aren’t many details surrounding this but the guitarist has been with the band for ~12 years. He will be replaced by guitarist Mark English (Monstrosity).
There was no official announcement in regards to this, but the line-up details have changed across the Deicide social networks which is telling enough. Jack will surely be missed.
Further details may be coming soon.
