Mos Def (Dante Terrell Smith) — rapper, actor and cultural figure

Early career and musical beginnings

Mos Def began performing in New York as part of the collective Urban Thermo Dynamics and gained attention through guest appearances on albums by artists associated with the late-1990s independent scene. He formed the duo Black Star with Talib Kweli; their 1998 album, also titled Black Star, is regarded as a landmark release for its lyricism and themes of cultural consciousness. Mos Def became closely associated with the roster and spirit of Rawkus Records, a label that helped bring underground and alternative hip hop into wider view.

Solo work and musical style

As a solo artist Mos Def has released several full-length albums, mixing rap with influences from soul, jazz and spoken word. Notable solo records include Black on Both Sides (1999), The New Danger (2004), True Magic (2006) and The Ecstatic (2009). His music is often described as socially aware and eclectic in production, with lyrics that address identity, politics, personal reflection and cultural history. He is also recognized for a flexible vocal delivery that moves between melodic singing and rapid spoken rhyme.

Activism, identity and name change
