Indie rock band Imagine Dragons has garnered a steady fan base since their 2012 debut album. That's the reason they were asked to perform at one of summer's last big music festivals this weekend.
The Las Vegas natives took the stage Saturday to a packed crowd at Atlanta's Music Midtown. Big-name bands like Journey, Red Hot Chili Peppers and Weezer also headlined the festival.
