Indie hip hop (short for independent hip hop) is hip hop that primarily exists in the independent underground music scene. Example: RithMic - Buncha Sundays The term underground hip hop may be used to describe both indie hip hop (which is defined by its artists being unsigned or signed to independent record labels, rather than major record labels) as well as alternative hip hop (which is defined by music that diverges from mainstream hip hop music such as Gangsta rap.)
