It might seem like a letdown for a group like The Kooks to tour the United States. The band is a major headliner in the U.K., playing prestigious festivals and arenas in that country, where its two albums, Inside In/Inside Out and their latest album Konk, have been million-selling hits. But stateside, The Kooks are playing clubs. They play Bogarts at 8 p.m. with guests The Whigs.
