Unerground hip hop, underground rap, or undie (to draw comparison to "indie" or independent rock) is an umbrella term for hip-hop and rap music outside the general commercial canon. Independent record labels are the major supplier of underground hip hop, but artists who are not signed to any label represent the independent scene just as much as their signed counterparts. This non-commercialized hip hop is represented through its other elements as well, such as graffiti, b-boying (break dancing), turntablism (djing), freestyle rap, and beatboxing.
