Performance poetry has its roots in oral traditions but gained new life in the 20th century. The Beat poets popularized recording poetry performances, while the Nuyorican Poets Cafe created a space for live audiences. Poetry slams were founded in the 1980s as competitive live poetry events, helping make poetry more accessible. Slam poetry often focuses on personal identity and current issues, using rhythmic language and occasional music. Notable performance poets have included Gil Scott-Heron, whose proto-rap influenced hip hop, and Kevin Coval, who describes hip hop poetica as continuing ancestral narratives.
