I haven't really been a fan that long, but I think they're a great band! It really isn't a surprise they aren't all that popular. Most of the REALLY good bands aren't.
Their songs really don't mean anything to you until you've been through some life event that relates to the song. Their lyrics are insightful and deep-- and I'm pretty much smitten with this band too. Thank you very much for the comment and taking time out to read this article. :)
Anberlin was the band that got me into rock music in the first place. It's a shame they're not all that well known. Some of their songs are pure genius, like Cadence or Change the world.
