Tunisian underground music refers to music performed by Tunisian artists that play or compose in a style different from the established Tunisian mainstream (most notably classic Malouf or arab pop). Using the term underground to define a performing arts movement or scene in the Arab world, including Tunisia, takes on a slightly different meaning compared to the one generally understood when used in the western countries. Given that contemporary Tunisian mainstream music includes only a few different musical styles, underground music has come to include any artist or band that sings or composes in a different genre. For example, while there's nothing underground about reggae on the international stage, Tunisian reggae bands may still be considered part of the Tunisian underground scene. The underground music scene in Tunisia is growing fast, and in the past two decades there has been a considerable increase in the number of bands trying out all sorts of musical genres, moving the boundaries of what is considered underground.
