Alt-rockers 3 Doors Down, Staind and Hinder--who earlier this month announced plans for a late-summer tour--have added a number of new dates to their itinerary, including a formidable run through Canada. As previously reported, the outing kicks off on the Fourth of July, and more shows are expected. Though all three groups are scheduled to appear on most dates, Staind and Hinder will each miss some concerts, so Finger Eleven [ tickets ] will fill in on a couple of those dates.

Tina Turner's upcoming return to the concert stage has been met with such an overwhelming fan response that promoters have added several more arena shows to the outing. The initial round of North American dates went on sale May 10 and the first gig--set for Oct. 1 in Kansas City, MO--sold out in two minutes, according to organizers.
