from wikipedia:
In popular music, independent music, often abbreviated as indie, is
a term used to describe genres, scenes, subcultures, styles and
other cultural attributes in music, characterized by their
independence from major commercial record labels and their
autonomous, do-it-yourself approach to recording, publishing and
live performing.
