All wide smiles and “woah-oh” chants, the singer/songwriter's disarming and charming self is on full display here. Songs like “Shouting,” “Headphones On,” and “Giants” are vintage Nathanson, attacking cynicism with wide-open, foot-stomping sing-alongs. Show Me Your Fangs also expands his musical palette. Subtle nods to dance and hip-hop shift in and out. Strings add drama to “Disappear” while “Gold in the Summertime” is streaked with Oakland soul. Matt’s shining charisma and creativity is the biggest star here and what gives Show Me Your Fangs its bite.
