V ampire Weekend bassist Chris Baio exudes a happy demeanor, albeit a slightly weary one. Weary thanks to an unyielding touring schedule that finds him traveling to San Diego midway through an extensive tour of the United States; happy because there can be no reservation that his band have dominated 2010 from its very first month, when second album "Contra," an eccentric, multicultural pop adventure, hit the top of the U.S. Billboard chart.

Not only that, but on their imminent fourth trip to Japan, Baio will get to celebrate his birthday in one of his favorite cities.

"I can't wait to get to Japan; we're going to Nagoya for the first time, which is exciting," he says. "And it's my birthday in Tokyo! I turn 26 the night we play. What a place to celebrate. Have I got anything special planned? Not yet. It won't be anything too crazy, I don't think. Just some good Japanese food for dinner. After a good show, hopefully."
