Underground rappers and brothers-in-beards Sage Francis and B Dolan bring the heat and street spirit of the New York spoken word scene to a yurt in St Andrew's Square. Seasoned performers and activists, the pair leave little time for stage antics or audience banter as they launch into a packed hour of polemic poetry that combines a fierce love for the revolutionary legacy of hip hop with sharp insights into the personal and political.

Although Strange Speech, Famous Development is their debut show together, and their first at the Fringe, the two poets have been contemporaries for years and that friendship shows on stage. Their repertoire of poetry, songs and storytelling works a little like a performed conversation – two poets passing tales back and forth, sparking off each others' tangents and ideas to form a kind of dialogue, rather than just performing a pre-ordained set.

They pivot between hindsight on high school to the commercialisation of hip hop and commentary on post-9/11 paranoia with finesse and black humour, but no two shows will have the same content, as the two develop and fine-tune over the course of the festival.

Stand in the Square, until 27 Aug (not 15, 22), 1.40pm, £14.
