What?! You’ve never heard of Wintergatan?
Some years ago I was turned onto the Swedish group, Detektivbyrån, who at the time sounded a lot like Yann Tiersen (of French movie “Amelie” fame). Over time their arrangements became steadily fuller, more complex, and inventive. They’ve now reformed as Wintergatan and are as clever and fun to listen to (and watch) as ever.
Here are a couple videos they put out to promote their debut album, which released this Spring. The second doesn’t have an accordion in it, but rather a melodica, which is close enough for me, especially since the song and video are so wonderful.
