Now that we know Jack and Meg aren't of blood relation, the Dead Weather has us wondering about Jack and Alison. Less than a year after its debut, the band releases album No. 2, an even more seditious shouting match than the first. If you like your rock with luster, step away. This is abrasive and abusive. The guitars (mostly credited to Dean Fertita) gurgle and grate with every bit of raw energy a six-string is meant to symbolize; Mosshart sounds like she's trying to scream her way out of an asylum, even sniggering through "I'm Mad"; White retorts with seething doses of sibling-like rivalry.
