Emo or Grunge is a GENRE of rock music that emerged in the late 1980s and early 1990s. It is characterized by its dark, emotional lyrics and distorted guitar sounds. The GENRE has been associated with alternative rock, punk rock, and indie rock. Emo and Grunge are often seen as two sides of the same coin, with Emo being more melodic and Grunge being more aggressive. Both genres have had a lasting influence on modern rock music.
