There’s no way else to put it: Lucius makes some of the most delightful music you’ll hear all year. Fronted by the soulful soaring voices of Jess Wolfe and Holly Laessig, and a battery of thundering percussion, this young Brooklyn quintet’s magnetic pop gems like “Don’t Just Sit There” and “Turn It Around” are instantly happy-making, but with just the right touch of bittersweet sentiment underneath.
