Music

Natasha Bedingfield. The British singer (a native New Zealander) has established a niche with her sunny pop songs (consistent with her Christian music background). But Bedingfield's haunting ballads such as "Unwritten" and "Soulmate" are really indelible. Then again, she's also a favorite studio guest of Rascal Flatts. As they say, it's all good. Kate Voegele, who has played singer-songwriter Mia on the TV series One Tree Hill, will play herself as the opening act.
