So, this song doesn't adhere strictly to the idea of being a song by a band I had heard before that either blew me away or changed my opinion on them, mostly because I couldn't think of any songs that fell into that category. That requires its own conversation on first impressions of music and whether or not those can be overcome, but I digress.
The song is Face Down, by White Lung. I came upon this band completely by accident, skimming through an article about music to check out on the old sports and pop culture website Grantland. The video was in the article, among others. If the description caught my attention I'd see if the sound appealed to me, something I can usually determine pretty quickly (again, requiring a conversation about first impressions). So the description of the band is, to paraphrase, feminist punk, and that catches my attention enough to get a listen. Within thirty seconds I am hooked, within an hour I have listened to that entire album and I am now an avid fan of the band. The guitar is amazing, the lyrics and vocals fierce and the drums pound like crazy. And I might never have heard any of it if I hadn't happened onto a random video posted in an article I was skimming through.
