Submissions for the NPR Tiny Desk contest closed at midnight last night, and of course most musicians waited until the last minute to record themselves performing a song in or around a desk to win a prestigious spot in Bob Boilen’s online concert series. Today YouTube is awash with video submissions, so this week we’ll highlight some of the best from our favorite DC bands and musicians. Today we’ve got a new unreleased song from acoustic folk experimentalists Humble Fire called “Northern Lights”. If you haven’t yet, grab their debut album The Great Resolve for whatever price fits your budget.
