Underground music refers to music that is produced outside of the mainstream commercial music industry. It often includes genres like punk, indie rock, hip-hop, and electronic, and is typically characterized by its DIY (do-it-yourself) ethos. Artists in this scene often prioritize artistic expression over commercial success, leading to innovative sounds and unique lyrical themes. This type of music is usually distributed through independent labels, online platforms, and live performances rather than traditional radio or major record labels. Underground music communities often foster a sense of belonging and support among artists and fans, encouraging collaboration and experimentation.
