U2: Summer Live Preview 2010
Ticket prices: $30-$250
The tour's unique staging provides the biggest stadium capacities ever. U2's 360° trek was the top ticket seller of 2009 at more than 3 million in attendance and $311 million in gross from just 44 shows-all sellouts. The band has 16 North American and 22 European shows scheduled for this year.
Outlook: U2 is on the road toward the highest-grossing tour in history as it begins to usurp the Rolling Stones and flirt with $600 million in box office. The tour's producer, Live Nation Global Touring chairman Arthur Fogel, calls the 360° trek "the mother of all tours."
