“She’s a Gun,” the new single from Godcaster, plants itself in a funky-glam space. The ticking of keys creates an anticipatory feel. However, it sits back in a groove, momentarily lapsing in a chase before falling back into its casual surroundings; then gets wild again. It has an eccentric, experimental aesthetic, meshing the strange with a shake-your-hips sentiment. Within a single lyrical line, a lot of territory is traversed.
