2014 has been a banner year for Hiss Golden Messenger with the release of their breakthrough album, Lateness Of Dancers. After working at it for so many years, though, they’re not going to stop there: the country-rock duo are planning to release a new EP, Southern Grammar, at the beginning of next year. The EP includes a few new songs and a live version of the title track, which the group brought to The Late Show With David Letterman last night. If you haven’t experienced the live power of Hiss Golden Messenger, this is a friendly reminder that you should correct that as soon as possible. You can check out the performance below:
