Leave it alone and let nature dispose of it. But life won’t be easier if noisecore toastmaster-general Otto Von Schirach is left undead to roam the earth, would it? Global is a spectacular bastardization of gangsta posturing and LP5-era Autechre’s Yellow # 5-sweetened discord. Such delinquency can pique nostalgia for the “laptop-punk” Class of ’01, but it now feels quaint. Yet Otto is still an agile entertainer with the bloated liver to prove it. “G4 Scramblin” pits muggers eyeing Steve Jobs’ latest model, while “Goat Sperm” is splattergore-metal on par with Mr. Bungle. Otto’s beat-crunching provides garlic-pill ecstasy in “Shine Yogurt” and “Iron Blood Saw.” Just quarantine Global and you’ll be safe.
