All the rock stars and pop idols are crawling out of their caves now that the warm weather is here, which means that the big acts will be bringing their North American concert tours to your city sometime soon.

One of the biggest concert tours to watch out for is Coldplay's Viva La Vida tour. These guys are hitting all the major cities. I'm actually going to be in Boston when they get there so I might check them out.

Neil Diamond is also back on tour and bringing the hit parade to your town. He's making sure no city will be left un-rocked, with over 40 shows scheduled during the summer, including four New York concerts.

But the concert I'm most looking forward to this summer is Radiohead at the Molson Amphitheatre in my hometown of Toronto. They're not hitting all the major cities in North America this time around, but are strategically playing large "open space" venues in most of the major regions. So you might have to drive 6 hours to see them, but it'll be worth it. Think of it as a one-band traveling Woodstock.

There are many more awesome summer concerts this year, so check out our listings in your city and mark them down on your 49st calendar.
