This is the title track of Swedish folk duo, First Aid Kit's, second album. The two sisters explained the title of the set to The Sun: "A lion roaring is essentially an emotion being expressed. We wanted to express our emotions more 'loudly' and more clearly with this record. This is reflected in the lyrics as well as in the arrangements."
First Aid Kit hooked up with Bright Eyes guitarist Mike Mogis to produce The Lion's Roar in Nebraska. They explained to The Sun how the collaboration came about: "Since we heard Bright Eyes, our biggest dream has been to work with Mike. We never thought we'd actually get to do it, let alone this early on in our career. After Monsters Of Folk's (which Mogis plays in) show in Stockholm in 2009 was over, we went backstage to meet them and gave them our CD. We were really nervous and starstruck. A year later (Bright eyes frontman) Conor Oberst and Mike Mogis showed up when we played at Austin City Limits festival in Texas. They had listened to the CD and loved it. Later we got a message from our manager saying Mike wanted to produce the record. We were like "Hell yeah! Let's do it!"
