Underground rap is a subgenre of hip-hop that focuses on independent artists who often operate outside the mainstream music industry. These artists typically prioritize artistic expression and authenticity over commercial success, often addressing social issues, personal struggles, and cultural themes in their lyrics. Many underground rappers release their music through independent labels or self-publishing, using platforms like Bandcamp and SoundCloud to reach their audience. This scene has produced influential figures such as MF DOOM and Aesop Rock, who are known for their complex wordplay and unique styles, contributing to the diversity of the hip-hop genre.
