American rock band The Killers formed in 2001, consisting of four members including lead singer Brandon Flowers. They have released three albums with a fourth coming this summer. The song "Mr. Brightside" was originally written as a tribute to band members' mothers but takes on a dark tone. The song's music video raises awareness about sex trafficking through partnerships with various organizations. The song has a slow, ominous feel that builds in dynamics and pitch until climaxing in yelling and crashing sounds near the end.
