《歌之径》系列致力于展示纳米比亚北部的埃托沙盐沼。该盐沼覆盖了4760平方公里，甚至从太空也能看到。埃托沙盐沼是一个大型的内流盐沼，周围环绕着天然泉水和盐生草地及灌木丛。大群的哺乳动物在平原上游荡，以满足它们的盐分需求。它们的足迹形成抽象的图案，将这片平坦的盐沼变成一件艺术品。长时间的精心规划、直觉以及大量的运气，是在正确的时间出现在正确的地点以发现这片风景隐藏的秘密宝藏所需的一些因素。沉默的《Songlines》以视觉诗歌的形式，向这片令人难以置信的景观致敬。
Songlines is dedicated to the Etosha Pan in the north of Namibia. The Pan covers 4760 square kilometers and is visible even from space. The Etosha Pan is a large endorheic salt pan. The pan is fringed with natural springs and halophytic grass and shrub lands. Large herds of mammals roam the plain to cover their salt requirements. Their tracks form abstract patters and change this flat pan into a work of art. A combination of long and tedious planning, intuition and a good portion of luck are some of the factors needed, to be in the right place at the right time for the landscape to share its secret treasures. Silent Songlines in form of visual poems – a tribute of this incredible landscape.

罗兰·布卢姆出生于1966年，在格拉布斯，现居住并工作于列支敦士登的沙恩。曾在卢塞恩爵士学校和卢塞恩音乐学院学习音乐。主要作品是抽象的航空摄影。对景观中抽象、结构和图案的迷恋以及对音乐的热情在他的图像中得到了共鸣。他的摄影作品非常接近绘画，真正意义上的“用光作画”就是摄影。
