Dripfed drops in at Blast-O-Mat on March 20

To a lot of people with mostly mainstream sensibilities and cultural affiliations, grindcore, crust and death metal will always just sound like a bunch of noise with terrible vocals. But a band like Dripfed — and most of the acts that probably inspired it — found that a splintery guitar sound mixed with a savage, breakneck pace and animalistic vocals reflected the anomie of modern society and the hurried way in which we’re all supposed to increase our efficiency to serve the monolithic corporate machine better than some over-processed pop ditty. What does Dripfed (due Tuesday, March 20, at Blast-O-Mat) bring to the equation to set itself apart? An engrossing dynamism whose quiet moments of focused intensity give the rest of the brutality contrast and a deeper emotional impact.
