Rock and roll attitude logo that pops against a black background, with clean lines (not cartoonish) and spot color(s), featuring a Gibson SG guitar smashing vertically into the ground causing a Hulk-smash upheaval (perhaps with emanating flames) where the resulting shockwave forms the name GROUNDWAVE below in stylized font (All Caps) coming at the viewer, slightly tapered at the ends and slightly bulging in the middle, in three dimensions like the ring at the base of a mushroom cloud, with a guitar cable running (splitting?) horizontally through the name in the form a seismic or sound wave. Using The Monumental Triangle ala Da Vinci, the image width and height should be proportioned so that the logo can ideally fit in a circle (bass drum head) or square (bar coasters). 

The designer developed a clever concept in response to our draft, made requested updates to help us select it as the winning design, and then made additional revisions at our request to fine tune the logo.
