The best things in life are often those that you stumble upon — the happy accidents that seem to be some combination of serendipity and joy. When I ran across this video on a friend's Facebook wall, I knew it was something we'd want to share with A Plus.
Árstíðir is an Icelandic folk group that, according to their website, was formed in 2008 after the stock market crashed.
Within six months they were at the top of the Icelandic music charts and by 2010, were touring, despite the eruption of Iceland's Eyjafjallajökull volcano, which disrupted travel around the world.
In 2013, however, they gained international recognition thanks to the video you're about to see. Captured by a friend, the clip is of the group performing the 12th century Icelandic hymn "Heyr himna smiður" ("Hear, Smith of Heavens") in Wuppertal, Germany's BürgerBahnhof train station.
It's quite unlike anything you've probably heard from a busker.
