The sounds of Celtic harp will ring in Trinity Church Wednesday, Oct. 5, as the Oasis of Music presents harpist Penny Amundsen in a free concert, from 12:30 to 1 p.m.  “I was a harpist disguised as a legal secretary, Amundsen said. “Then, eight years ago, I decided to make my lifelong ambition come true. I signed up for lessons at 317 Main in Yarmouth and have never looked back.” Her music is a blend of traditional Celtic and classic rock, with some jazzier tunes thrown in for fun. The recent release of her self-recorded CD, which can be purchased through her Facebook page, marks another step toward a musical career for the Raymond resident.  Trinity Church is located at 2?47 Bates St., Lewiston.  FMI: call 344-3106.
