Heavy metal in 2015 doesn’t sound much like heavy metal in 1975, except when bands such as Demon Eye play it. Despite the prevailing trends of so-called extreme metaldeath, thrash, doom, grindcore and so onthe Raleigh quartet returns the leaden stuff to its roots.

Their new sophomore album, Tempora Infernalia, takes cues from proto-metal lords like Deep Purple, Black Sabbath and Blue Cheer. Instead of an onslaught of indecipherable growls and assaultive riffing, Demon Eye divines righteous grooves from strong melodies and succinct songwriting.

Demon Eye emerged as an outgrowth of Corvette Summer, a good-times cover band dedicated to excavating hard rock deep cuts of the ’70s. Demon Eye isn’t a cover band, of course, but their attention to a fundamental principle of metalmaking a song both heavy and hookymakes their material feel classic.
