Blending moody dub musings with stomping power chords and the odd burst of thrash rock, Dub Trio emerged a few years back as abstract instrumentalists picking up where Bad Brains and Faith No More left off. Cool Out and Coexist, a live set recently recorded at Brooklyn’s Union Pool, sees the band shifting several gears towards the heavy-metal end of the spectrum, with most tracks now defined by DP Holmes’ screeching guitar; one gets a sense of their powerful impact on stage, and even if the disc is slightly less subtle than its studio predecessors, fans of their live sets will not be disappointed.
