A new CD by jazz artists Garry Dial and Terry Roche has just been released, containing jazz interpretations of numerous national anthems.
I mention it in passing because they’ve chosen to include La Espero, the Esperanto anthem. (Can’t call it a national anthem, because obviously the whole point is that it isn’t of any particular nation).
You can listen to clips and buy the album at CDbaby.com.
If you don’t already know it, you can hear a more traditional version of La Espero over at imeem.com.
