The highly theatrical Estonian punk/metal/WTF band Winny Puhh have been around since 1993 or so, but online audiences around the world are discovering them by way of this video: the band performing their song “Meiecundimees üks Korsakov läks eile Lätti” on Eesti Laul 2013, the semifinals for the Estonian slot in Eurovision Song Contest 2013.
Death and Taxes magazine has a good backgrounder here, with more of their videos, all of which are weird, some of which are NSFW.
Listen to their songs here.
* I know this is gonna shock you, but their name translates to "Winnie the Pooh." HT: Syd Garon!
