Who knows why some albums are a success and others go unsung? Las Vegas band Imagine Dragons hit one of those pockets of luck with its latest album, Night Visions. While the new album may seem like a breakthrough, the group has been working hard for years — touring extensively, writing constantly — to garner the acclaim it's currently enjoying. The bandmembers rented a house together in their formative years, playing covers in bars to near-empty rooms to pay the rent; before that, frontman Dan Reynolds reportedly drew inspiration from seeing live shows of bands like Arcade Fire and Jack White. Clearly, all that hard work has paid off.
