Modern metal fixture Zakk Wylde first came to musical prominence when he was just 19, tapped by Ozzy Osborne himself to serve as lead guitarist and co-writer for his band. After serving his mentor loyally for many years on numerous records and tours, Wylde, who today looks like an axe-wielding Viking, branched off to create a personalized outlet with Black Label Society. A strange brew influenced by Metallica, Skynyrd, and of course, Black Sabbath, Black Label Society delivers plenty in terms of lightning-quick riffs and licks, chugging distortion, and unapologetic, guitar-driven sludge (not that the band is devoid of all acoustic instrumentation or piano colorings). The group’s most recent CD, “The Song Remains Not the Same,” is a stripped-down companion piece to its 2010 album, “Order of the Black.” Black Label Society is scheduled to perform at the National on Sunday, June 5, at 7 p.m. $28-$32. 612-1900.
