Kanye West and Jay-Z, whose new collaborative album "Watch the Throne" will be released next month, will also tour together, it was announced Monday by concert promoter Live Nation. 

The two rappers will go on a 24-city tour, also called "Watch the Throne," that will kick off in Detroit September 22.

The tour includes stops in Washington - on Sept. 29 at the Verizon Center - and Baltimore - on Nov. 1 at 1st Mariner Arena.

Tickets go on sale August 8, the same day the album is released exclusively on iTunes. Promoter Live Nation has an additional incentive for the live show: those who purchase tickets will also get a digital copy of the album, which retails for $11.99. Live Nation did not include the cost of tickets in the press release.

When the show hits Baltimore, it'll be the first appearance in the city by Jay-Z in nearly two years. In 2009, he performed at 1st Mariner also. Kanye West last performed in the area in 2008, at the Virgin Mobile FreeFest. The two performers have appeared as guests on each other's tours, but have not previously toured together.

If there's anything surprising about this announcement - a tour has been expected - is that they're playing at 1st Mariner, when a double-bill of the two - a trend in the concert industry this year - is one of the few combos that could justify a stadium concert.

"Watch the Throne," the album, is highly anticipated and its song "Otis," the second single that's been leaked, has already generated a small controversy. Wesley Case reviews it here.

Tickets for the tour will be available for a pre-sale on Thursday on the website www.LiveNation.com/WatchTheThrone. Tickets will go on sale to the general public August 8 at 10 a.m.
