Better still are groups like Broken Social Scene, which keep you guessing while lobbing one wobbly, janky curveball after another on Forgiveness Rock Record (Arts and Crafts), dipping toes into puddles of foghorn-like electronics ("World Sick"), toying with dynamic highs and lows while embracing the rock-out ("Meet Me in the Basement") and the close-up ("Sentimental X's"). You forgot that indie rock could still do it, but songs like "Forced to Love" and "Sweetest Kill" jolt you out of cozy complacency.
