Pearl Jam continues to add shows to its 2005 tour itinerary, the newest being an Aug. 29 date in Missoula, Mont., where bassist Jeff Ament went to college. Proceeds from the gig at the Adams Center will benefit Montana Senate president Jon Tester’s bid for the U.S. Senate. Tickets go on sale July 23 via Tickets West.
The benefit comes on the heels of a recently announced Sept. 1 show in George, Wash., which sold out in three hours, and a Sept. 30-Oct. 1 stand at the Borgata in Atlantic City, N.J., which sold out in two minutes. In between, Pearl Jam will play a 16-date Canadian tour beginning Sept. 2 in Vancouver and open a Sept. 28 show for the Rolling Stones in Pittsburgh.
The group is still at work on its as-yet-untitled eighth studio album, due early next year via J Records.
