Tanzania's entertainment culture is most vivid in its music. Bongo Flava — the Tanzanian hip-hop and R&B synthesis that developed in Dar es Salaam in the 1990s and became East Africa's dominant popular music — fills clubs and outdoor venues with an energy specific to a city of Dar's scale and youth. The taarab music tradition of Zanzibar — an orchestral popular genre blending Arabic, Indian, and African musical elements, performed by large ensembles at weddings and community events — is one of the most distinctive social music forms in East Africa. The Sauti za Busara world music festival in Zanzibar's Stone Town, the Dar es Salaam Film Festival, and the Karibu Music Festival bring formal entertainment to a country whose most vivid music culture is often on the streets rather than on a ticketed stage.
