What is indy music?

indie music, often abbreviated as indie (from independent) is a term originally 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.[1] The term has since become increasingly popular and is now often used to describe anything in music that is characterized by its perceived indepency from mainstream or pop culture as a whole. As such, it can be seen as a synonym for alternative music
