On their previous Booth features, Boston-based pop duo Aer showcased a mellow, reggae-tinged style that screamed “summer.” Rather than going into hibernation now that a chill has begun to creep into the air, David von Mering and Carter Shultz have switched things up and adopted a more peaceful, autumnal sound on Won’t Laugh, single numero uno off their next full-length. While the duo’s high-energy, sung-rapped bars are present and accounted for, the record incorporates some unusually pensive guitar work and a sweeping, Coldplay-esque hook melody. Tyler Yee directs the accompanying visuals. Aer (the LP) is scheduled to drop independently on January 21, 2014. In the meantime, of course, you can keep it locked to The DJBooth for the latest song releases off the set.
