Screamo
Screamo (also referred to as skramz) is a hardcore punk-influenced subgenre of emo that emerged in the early 1990s, featuring a large amount of screamed vocals and combining musical intensity with "willfully experimental dissonance and dynamics." It was pioneered by San Diego bands Heroin and Antioch Arrow and developed in the late 1990s mainly by bands from the East Coast of the United States such as Orchid, Saetia, and Pg. 99. Screamo is strongly influenced by hardcore punk and characterized by the use of screamed vocals. Lyrical themes usually include emotional pain, romantic interest, politics, and human rights.
