Lowkey, a giant of British hip-hop, will be headlining a concert on Sunday to mark the 20th anniversary of Refugee Week in London.
Despite previously announcing his retirement, Lowkey returned last year to music with a batch of releases and singles focusing on refugee issues and freedom of movement.
His politically-charged lyrics cover issues as diverse as global affairs, race and poverty.
Lowkey has participated in numerous aid missions to Palestine as well as campaigning in and around his community of Grenfell.
The festival is hosted by Refugee Week, a national programme celebrating the contributions refugees make to the UK.
It emerged in 1998 to counter negative attitudes to migrants and always centres around the week of World Refugee Day, which is held annually on June 20.
Counterpoints Arts is a co-organiser, and it supports and produces arts by and about migrants.
During the finale of Refugee Week, Lowkey will be joined by Native Sun and Palestinian rappers EbsilJaz.
The group will debut a new single called Escape from Yarl's Wood that focuses on talks between a lawyer and translator in a detention centre plagued by human rights violations.
The Yarl's Wood facility has become a key focus of activists fighting against deportations.
The song is both in English and Arabic, and looks to reach a diverse audience including migrants.
