A pop chameleon with deep, commanding pipes, Chris Daughtry agilely flips between crunchy modern rockers, countrified weepers, and high-energy anthems powered by club beats. Mere months after his 2006 appearance on American Idol, the singer found himself riding “It's Not Over,” a brawny, post-grunge ode to resilience, to the top of the charts. Yet another smash, “Home” is a dramatic heartland power ballad sweetened with strings. On “Supernatural,” Daughtry jumps to the upper reaches of his range while staccato guitars fall in lockstep with a groove shaped by an ecstatic EDM-like pulse.
