I'm posting a video by a Finnish heavy metal band every day in June in support of the Helsinki in 2017 Worldcon bid.
Today's song is "Death and the Healing" by Wintersun. I've seen Wintersun live twice, and while they're great fun, it always leaves me a feeling a little bit like I haven't studied properly for a test. Because real Wintersun fans know *all* the lyrics. (It might have been a performance of this song during which I saw the guy in front of me grab his buddy and say, "You know the words to this song, right? Because if you don't, we can't be friends anymore." Fortunately, his buddy did know the words, and thus the friendship was saved.)
Anyway, when I've seen Wintersun play this song, they usually stop playing for a bit in the middle so the audience can belt out a few rounds of the chorus. It's pretty spectacular.
