With a military drumbeat and a story that’s equal parts Billy Joel and Paul Simon about getting “higher than the Empire State,” NYC indie-pop group fun. began one of the most infectious earworms of 2012. That anthem, “We Are Young,” went on to win a Grammy, go quintuple-platinum, and hit No. 1 in at least 12 countries. Since then, they’ve released two more hit singles, and their album Some Nights has attained the increasingly rare achievement of platinum status. Tonight and tomorrow, they return to their hometown for a pair of gigs on Pier 26, overlooking the Hudson River. Joining them are the equally indie-pop minded duo Tegan and Sara, whose latest album, Heartthrob, found the twin sisters diving into catchy synth backdrops. Wear dancing shoes.
