I'm still processing Sleigh Bells' Reign of Terror, but my preliminary take is that if Treats was their Fever to Tell, this is their It's Blitz, trading a monochromatic assault for a more varied, moody approach. That analogy doesn't entirely work, of course: Reign of Terror doesn't represent a total sonic reconfiguration and, honestly, comparing bands just because they both have female singers is rather lame. But I do like how the new disc finds the duo branching out. But with that said, the first single, "Comeback Kid," shows them sticking to their noise-pop bread and butter. That's fine: It rocks.
