An Overnight Low, which features Biddeford native Chad Walls, third from the right, will perform at 9 p.m. Thursday, Sept. 7 at Portland House of Music. Walls, while obtaining his doctorate in the United Kingdom, was inspired to write songs about his travels. An Overnight Low has released a trilogy of albums, all based on the experiences had by Walls: “Euston,” “Picadilly” and “Waverley,” which was released in June. Dominic Lavoie and Bri Lane will also perform at the Sept. 7 event. The triology of albums is available at Bull Moose Music. (Courtesy image) 13p1.jpg
