U2 and Live Nation have confirmed the first tranche of stadium dates on the band's global "360°" tour.

As first revealed on Billboard.biz on Friday (March 6), the tour, produced by Live Nation Global Touring and sponsored by "smartphone" brand Blackberry, kicks off at Barcelona's Nou Camp soccer stadium on June 30. The first tickets to go on sale for the "in the round" shows will be for Milan and Gothenburg (March 13), followed by Amsterdam (March 14).

In a statement issued today, the band's manager Paul McGuinness said: "U2 has always been at their best when surrounded by their audience, this staging takes a giant leap forward. With 85% of the tickets priced at less than €95 [$119.40], general admission floor tickets priced at €55 [$69.12] and at least 10,000 tickets at every venue priced at around €30 [37.70], we have worked very hard to ensure that U2 fans can purchase a great priced ticket with a guaranteed great view."
