On the subject of gypsy jazz (yes, it’s an actual thing), some bronies came up with one of the best and most unique examples of the genre.
This is Russian Gypsy Jazz, and it’s AWESOME.
Say what you will about bronies and the MLP fandom in general (I’m staying out of that flame war), but some excellent music has come from them, the above being an excellent example.
Apparently, this is a Russian gypsy jazz version of an English song from an MLP parody called “Friendship is Witchcraft”, so yeah, I’d say it counts as being obscure.
So sit back, relax, and give Russian gypsy jazz a chance.
