Is hard to do. But it's kinda fun to watch and can make for some intriguingly awkward music. This summer, the Jonas Brothers continue their bid for power pop legitimacy with a world tour supporting the trio's fourth album, "Lines, Vines, and Trying Times" -- a set inspired by the sexy Kings of Leon and guru-level hitmaster Neil Diamond and due out June 16.
