Kelly Clarkson’s rich voice brings a burning emotional current to the hi-octane riffs of “Hear Me,” “Behind These Hazel Eyes,” and “Breakaway.” “Since U Been Gone” echoes the catchy hard rock of the Foo Fighters, and there are few female singers who can hold their own with such macho material. Clarkson blends elements of R&B, alternative rock, and adult contemporary and makes it all her own.
