'Blunt Force Trauma,' the pulverizing new album from Cavalera Conspiracy, is the musical evocation (and possibly even the literal equivalent!) of the sensations following a car crash. Abrupt, hyper-charged and possessed of some of the fiercest riffage and percussive bombardment of the Brazilian born Cavalera brothers' storied career, it's a sophomore-slump defying declaration that the Cavalera Conspiracy was no mere one-off, fluke or temporary side-project.
