Portland’s Red Fang may have snagged the public’s attention with its lowbrow-but-high-concept music videos (e.g., an exploration of many items procured from a grocery store can be rammed with an old station wagon), but its music stands firmly on its own. It’s in the lineage of fellow red-blooded, working-class, beer-and-weed-fueled metal bands like Baroness, Kylesa, and The Sword — but better. The band really hits the gas pedal on its latest, Whales and Leeches: Opener “DOEN” explodes with a stoner-y riff and hyperactive drumming, while “Dawn Rising” settles into a sludge groove with operatic, Chris-Cornell-invoking vocals. Throughout the album, there’s a tongue-in-cheek lightheartedness, showing that the band isn’t afraid to mock the tropes it obviously worships at the same time. It’s a refreshing take on a genre in which self-seriousness is too often the norm. The band will play at Slim’s (333 11th St., San Francisco) this week with The Shrine and Indian Handcrafts.
