Last time The Black Keys played at the LC, frontman Dan Auerbach was feeling under the weather and apologized, a few times, for not being at his peak.

Last time The Black Keys played at the LC, frontman Dan Auerbach was feeling under the weather and apologized, a few times, for not being at his peak.

No apologies were necessary, as the blues-rock duo banged out a concentrated rock performance with some of the tightest sound I've ever heard at an outdoor venue.

That tour, supporting "Attack & Release," showed the Keys had augmented their signature bare-bones howling guitar and thunder drums sound with periodic keyboards and basslines in well-executed production - both in studio and onstage.

This time around, the Akron natives are touring in support of another stellar studio effort in "Brothers," which has the same fleshed-out sound even though Danger Mouse only produced the single "Tighten Up."

If their last stop in Columbus (and more recently at Lollapalooza) is any indication, The Black Keys' raw intensity will be bolstered by minute soundscapes justifying the sold-out show - even if Auerbach suffers from the sniffles again.
