You don’t have to sell out the Georgia Dome or Philips Arena to find happiness in the faces of a crowd; you can find it volunteering and sharing your music with those in need. Jamie Balmer and Joseph Ricker are a group known as Duo Orfeo, a classical guitar music group from Massachusetts. They volunteered their time and musical talent Sunday afternoon to bring happiness to those at the Good News at Noon homeless shelter in Gainesville.
