Few of us make much out of the endless weekend hours we spend together when we're young. Draping ourselves throughout our friends' houses and airing out the angst and dreams and heartbreaks that will shape us before they fade away with time, we may make mixtapes, or weave friendship bracelets, or simply craft inside jokes and rosy memories to cherish in years down the line. But for Dublin folk rock quintet Little Green Cars, those Sunday afternoons may have built the most important adventure they'll ever take.
