All child prodigies grow up and most burn out, with only the lucky few maturing into capable adult talents that make it over the long haul. At age 30, Ben Kweller is now more than 14 years removed from the dizzying major-label bidding war and late-night talk show performances that greeted his teenage band Radish; but the father of two still sounds like a fired-up and frustrated adolescent on his just-released sixth solo album, Go Fly a Kite. That's not meant to be taken as a diss. Kweller's always been at his best when filtering Weezer's adenoidal fury through a classic singer-songwriter lens, and after a brief, awkward detour into traditional country and western on 2009's Changing Horses, he's back at the task with renewed fervor. Sure, he's not exactly showing off any range, just plenty of mid-tempo power-pop gems broken up by the occasional loping power ballad. But as usual, Kweller more than makes up in catchy melodicism whatever he lacks in innovation.
