U2 [ tickets ] has added new North American dates to its fall 360 Tour, which has seen the Irish rockers smash sales records each time the box-office windows open.

Newly announced cities comprising what the group is calling its "final 2009 concert dates" include shows in Raleigh, NC (10/3); Dallas (10/12); Houston (10/14); Norman, OK (10/18); Phoenix (10/20) and Las Vegas (10/23). On-sale dates are included with the complete itinerary below.

The tour gets underway with two shows (9/12-13) in Chicago, before moving on to Toronto, suburban Boston (Foxboro, MA) and East Rutherford, NJ, with a pair of nights in each location. U2 will hit 16 North American cities on the trip, which follows a run of European dates over July and August. The band's overseas schedule can be found at the official U2 website.

The tour sold 450,000 tickets Monday morning (4/6), when a new batch of shows went on sale, according to a press release, with the total number of tickets sold for the tour throughout North America and Europe now topping 2.5 million since the trek was announced in late March. The Oct. 25 performance at Pasadena, CA's 90,000-seat Rose Bowl sold out in a matter of hours, marking the largest concert performance to ever take place in the historic venue, as well as the quickest sell-out, according to tour promoter Live Nation.

Additionally, according to the band's publicist, 160,000 tickets for the July 24 and 25 concerts in Dublin, Ireland's Croke Park sold out in less than 40 minutes, leading to a quick announcement of a third show in the group's home city.

U2 previously announced a few of the opening acts that will join the band on tour. Snow Patrol will open the Chicago and Boston-area shows; Muse will handle opening duties for the NYC-area engagements; and The Black Eyed Peas are on board for the Pasadena date.

The upcoming tour, which begins with a 14-city European leg this summer, supports U2's recently released 12th studio album, "No Line on the Horizon," which debuted at No. 1 in 30 countries, including the US, where it posted first-week sales of about 484,000 copies.
