Emo - Derivative of punk rock music with emotional, introspective lyrics

"Emo is a rock music genre characterized by an emphasis on emotional expression, sometimes through confessional lyrics. It emerged as a style of post-hardcore from the mid-1980s hardcore punk movement in Washington, D.C., where it was known as emotional hardcore or emocore and pioneered by bands such as Rites of Spring and Embrace. In the early–mid 1990s, emo was adopted and reinvented by alternative rock, indie rock and pop punk bands such as Sunny Day Real Estate, Jawbreaker, Weezer and Jimmy Eat World, with Weezer breaking into the mainstream during this time. By the mid-1990s, bands such as Braid, the Promise Ring and the Get Up Kids emerged from the burgeoning Midwest emo scene, and several independent record labels began to specialize in the genre. Meanwhile, screamo, a more aggressive style of emo using screamed vocals, also emerged, pioneered by the San Diego bands Heroin and Antioch Arrow. Screamo achieved mainstream success in the 2000s with bands like Hawthorne Heights, Silverstein, Story of the Year, Thursday, The Used, and Underoath. - Wikipedia"
