Quilt has one of the most appropriate band names. Its music can be a soft, warm blanket with lovely harmonies, layers of textured drones and dreamy words. One standout song from the group’s current album, Plaza, is called “Padova.” It’s a galloping tune with a sad underpinning whose lyrics puzzles you. Now the Boston-bred band, with director Christopher Good, has produced a video for that song, a song named for a town in Italy. NPR watched it and the imagery of burning tables and flowers puzzled even more. So NPR asked Shane Butler, the writer, singer and guitarist for this Quilt song about it and what he wrote was so powerful, adding so much to the listening and viewing experience.
