We met up with indie rockers Islands in San Francisco’s South Park, where they traded their electrified tones for an acoustic palette “to invent a new rendition” of “Shotgun Vision” — and the new version works beautifully as bluesy hooks and clever harmonies rise to the surface. For more from Islands, also check out their melodic acoustic offering of “Here Here,” another track off their 2013 release, Ski Mask.
