Not long after his parents arrival from Sierra Leone via UK, Sahr was born in Fort Wayne, Indiana.

He has worked with Gerrit Timmers (Onafhankelijk Toneel, Rotterdam), Falk Richter (Berlin Schaubühne, Berlin), Del Hamilton (7 Stages, Atlanta), Walter Chakela (Windybrow, Johannesburg), Tim Habeger (PushPush Theater & Film, Atlanta), Made n da Shade/MC (Amsterdam).

Since relocating to Amsterdam in 2001, Sahr has worked as a theater director and developer with Rotterdam’s Lef and ACT Festival, and as a collaborator with Made n da Shade.

Under the primary influence of his work with Freddie Hendricks, as it relates to his creating of original works, integrating music into every layer of the developmental process, together with what he gained through close work with Made n da Shade and their extensive exploration into the weaving of interactive design technology throughout the base fibers of their theatre, Sahr used the laboratory of Dasarts and his encounters with Shu Lea Chang and Germaine Acogny to search for his own unique language and process, in an effort to lay a foundation that will hopefully allow him to all ways break new ground in his personal approach as a Maker.

His work Conversations with Ice deals with the question of value (who decides, who buys), within the context of the global diamond trade, Sierra Leone’s child soldiers, and its links to the Bling sub-culture in hip-hop.

Sahr has appeared at speaking engagements at art conferences in Northern Europe (2007–08) about the construction and development of Conversations With Ice, with invitations pending to present this work in Sweden and Tokyo.

In November 2008, Ngaujah received the Audelco Award (or "Viv award") for his work on the Off-Broadway musical Fela!, under the direction of Bill T. Jones, which explores the life and inspiration of the Nigerian composer Fela Anikulapo Kuti.
