The Aussie rockers' eight-country stadium tour starts in the U.K. on June 8, where they'll be backed by Offspring and Megadeth. (Rest of tour continues through June 24.) Milton Keynes, England.

It may be overambitious for Hultsfred to call its main stage Hawaii. But this three-day bash in rural Sweden (June 14-16) does enjoy almost round-the-clock sunlight and a stellar list of international acts — Limp Bizkit, the Manic Street Preachers and Aimee Mann — plus local artists such as Håkan Hellström. Hultsfred, Sweden. www.rockparty.se
