New York popsters The Postelles brought their upbeat bubble to the elegant stage of Idno in Reykjavik, as part of the Airwaves Music Festival. We caught up with the quartet -- Daniel Balk, David Dargahi, John Speyer, Billy Cadden -- right after their Airwaves gig and asked them to wax Icelandic for a minute before they headed back to New York. Catch them in NYC tonight at Bowery Ballroom or tomorrow at the CMJ PureVolume House after party. Or just catch ‘em kickin' it with the hidden people.
