With songs that range from relentless mid-tempo churns to subterranean crawls, BATILLUS (buh-TILL-us) cohere the extremes of heavy music into a surge of massive riffing, rolling over and descending on the listener with the force and intensity of a sudden storm. Concrete Sustain is the follow-up to their 2011 critically lauded Furnace long player, which Metal Underground recommended for fans of "massive riffs and being crushed to death in slow motion."
