I don't see this song around anywhere, so I'm going to assume it's pretty obscure. Probably up there in my list of all-time favorite songs.
My first introduction to Drum & Bass. So much nostalgia.
Abney Park itself is a pretty obscure band, but for the sake of staying on-topic, this is a great song that doesn't seem to get much recognition.
Unless you're a fan of the Metro series, you've probably never listened to this song before. A bit of a hidden gem, if you are into this style of music.
