The guys in Massachusetts groovecore unit The Acacia Strain have made an impressive career out of just barely setting themselves apart from the alt-metal pack by incorporating non-traditional elements like noisy samples and dense three-guitar composition. While the group's current four-piece lineup eschews extra live instrumentation, fifth full-length Wormwood (Prosthetic) exhibits a firm understanding of what makes The Acacia Strain attractive to listeners tired of the same old slicked-up death-metal tropes: thick sonic layers, solid grooves and a meaty, depthy low end.
