The Black Keys have added a second leg of dates to their first-ever arena tour of North America.

Fifteen concerts are booked for the new spring outing, which primarily focuses on West Coast and Canadian markets. The leg picks up with a previously announced show on April 24 at the Cynthia Mitchell Woods Pavilion in The Woodlands, TX.

Other scheduled stops on the arena run include April 30 at 1st Bank Center in Denver, CO; May 7 at the Rose Garden in Portland, OR; and May 14 at MTS Centre in Winnipeg, MB. The leg is presently set to wrap May 16 at Bradley Center in Milwaukee, WI.

Fan presales begin at 10 a.m. local time tomorrow, January 10, and onsales open to the general public over the January 13–14 weekend. Ticket prices follow a similar structure to the tour’s still-upcoming first leg, with face values running between $30 and $55 in U.S. and Canadian markets.

Onsales started early last month for the Keys’ initial 2012 tour leg, which will run throughout month of March. Several of those dates have already sold out, including a March 12 gig at Madison Square Garden, according to the band’s official Web site.

English indie rock band Arctic Monkeys is supporting both legs of The Black Keys’ North American tour. In the wake of initial onsales, that Keys-Monkeys billing briefly entered TicketNews’ exclusive concert rankings for the week ending December 11.

Based out of Akron, OH, the blues-rock duo already has more than a half-dozen albums under its belt. But vocalist-guitarist Dan Auerbach and drummer Patrick Carney didn’t break into the mainstream until the May 2010 release of the critically acclaimed “Brothers” hit No. 3 on the Billboard 200.

The pair has found similar success with its December 2011 release “El Camino,” which hit the charts at No. 2. The positive reception from critics and consumers alike has been enough to push The Black Keys out of mid-sized concert halls and on to arena stages.
