Trip to Caldera, an up and coming rock band from Croatia, searched for their new visual identity while growing on the music scene.
The design settled for a double circular frame encompassing the name's abbreviation. What stands behind this idea is mostly geographical; it's envisioned as a top-down view of a caldera (volcanic crater), where harmoniously oriented edges represent elevation contour lines like those on a map.
Resulting logo is sharp and readable, but fitting for ambitious rocky musicians.

Their music can be checked out here:
