Imagine an intriguing logo for "Echoes of the Unknown." The word "Echoes" appears prominently, with stylized letters reminiscent of moving sound waves. The lyrics are fluid and curved, creating a sense of mystery and movement. The word "of the Unknown" is positioned below, in a more solid and bold font, to contrast with the flowing lyrics of "Echoes." At the center of the logo is an enigmatic visual element, such as an abstract symbol or an icon that represents the unknown. It can be a mysterious sphere, an enigmatic silhouette or any other element that conveys a sense of mystery and curiosity. The color palette is composed of dark and deep tones, such as navy blue, purple or dark green, to evoke a climate of mystery and intrigue the viewer.
