Laura Thomas has a lot to say and definitely the voice for it. Her last album, "Step to the Wire," features politically charged and introspective ballads along with jabs at President Bush's foreign policy. She has Ani DiFranco, Alanis Morissette and Norah Jones in her sound, with a backdrop of blues and pop-rock inflections. But her voice is the main event. The Laura Thomas Band arrives in Richmond to play a benefit concert, along with Richmond's own Velvet Marias, for Iraq and Afghanistan Veterans of America. At the Capital Ale House Sunday, April 6, at 4 p.m. $12. 780-ALES.
