After all the hype had died down, and they’d played the last show of an extensive international tour, the members of Future Islands must have found themselves in an insecure place. In March 2014, the band’s popularity boomed all at once thanks largely to a breakthrough moment — their ecstatic performance of “Seasons (Waiting on You)” on The Late Show with David Letterman — and the subsequent internet craze that this moment spawned. By mid-2015, however, I imagine the natural uncertainties of being a band post-15 minutes of fame had set in. Would Future Islands be forever remembered as that band that played on Letterman? What could lay ahead for them now that their big moment of mainstream attention had come and gone?
