Alice Cooper [ tickets ] and Queensryche [ tickets ] will be on hand as support for the trek, which kicks off Sept. 5 in Binghamton, NY. So far, 12 cities appear on the group's itinerary (shown below), with more dates to be announced soon, according to a posting on the band's MySpace page.

The group--composed of Black Sabbath founding members Tony Iommi and Geezer Butler, along with interim Sabbath vocalist Ronnie James Dio and former Sabbath drummer Vinnie Appice--is currently touring Europe, with an Australian tour scheduled for later this summer. The band's complete overseas itinerary is posted at the tour's website.

The reunion of Dio and his one-time Sabbath bandmates came about when the musicians convened in a studio last year to record three new songs for the era-spanning Rhino compilation "Black Sabbath: The Dio Years," which hit stores in April.

The sessions "went so well that the band agreed to satisfy longstanding demands for a reunion tour," according to a press release.

Dio filled in for original Sabbath singer Ozzy Osbourne twice during the '80s and '90s.

The first US concert of the band's "comeback" tour, a late-March appearance in New York City, was taped for a CD/DVD combo, "Heaven and Hell Live From Radio City Music Hall." The set is due to hit stores Aug. 28 on the Rhino label.

Iconic hard-rocker Cooper, who spends much of his time these days hosting his syndicated "Nights with Alice Cooper" radio show, recently wrote an autobiography, "Golf Monster," which was released last month. Veteran prog-metal outfit Queensryche continues to tour behind last year's "Operation: Mindcrime II."
