What Are the Biggest Tours of the Year?

Unless Mick Jagger decides to resurrect the Rolling Stones, 2011's biggest tour will probably the final legs of U2's 360 tour. They start in Africa next month and swing through North and South America from April through July. Other definite tours include Lady Gaga, Neil Diamond, Kenny Chesney/Zac Brown, Foo Fighters, Red Hot Chili Peppers, Rush, Bon Jovi, Taylor Swift, Backstreet Boys/New Kids On The Block and Sade. It's also likely that Radiohead, Journey, The Cars and Britney Spears will hit the road. If ticket prices are kept down to reasonable levels this might actually be a good year for the industry.
