<光影>是我的一个朋友加盟华端口音乐后发表的第一首作品，由键盘手许明康作曲，主唱马马填词。歌曲的创作灵感来自于后现代主义摇滚音乐，而歌词是在马马于新西兰旅行期间，看到星光闪耀的景观后结合自己的经历谱写完成。 　　is the first single from A Friend of Mine since the band signed with Chinatown Music. The song was composed by Mingkang Xu (keyboards) under influence of post-rock, and the lyrics - a reflection of personal experiences - were written by Ma Ma (vocals) when she saw stars in the night sky as she was traveling across New Zealand.
