Tantric

When a near-metal band covers Fleetwood Mac’s “The Chain,” it has to know it’s tossing huge chunks of its potential audience overboard. Hugo Ferreira belting Stevie Nicks’ parts in a Drano-gurgling grumble is disorienting enough; the bona fide yingoes kick in when the harmony parts suddenly sound like they’re coming from the cast of American Chopper. Yet Tantric may turn out to be the best “date metal” band since the glory days of Journey. The day after the show, just ask couples who were in the front row if they’re glad they went Tantric.
