What are you listening to right now?

Buckethead - Sketches Of Spain (For Miles)
Man, how come I didn't listen to him before? He's a genius!

Eluveitie – Inis Mona
Melnitsa – Tebya Zhdala Ya (Inis Mona cover)

I didn't know that. The original is better.

Both are covers. And the original is called Tri Martolord - a Breton (if I'm not mistaken) folk song. Many people have covered it, both with the original lyrics and in different arrangements.
