Sebastian is an American rapper who emerged from the late 1990s–2000s Virginia music scene. Often identified by the single stage name Sebastian, he is best known for his association with his older brother, record producer and artist Timbaland. Public biographical details are limited; some sources report he was born in Norfolk, Virginia and has been credited under the family name Mosley.

Background and early life

Sebastian grew up in Virginia, a region that produced a wave of influential hip-hop and R&B talent in the 1990s and 2000s. That environment—characterized by inventive beats and close collaborations among producers and vocalists—shaped his musical outlook. Like many artists from that circle, Sebastian moved between recording sessions, guest appearances and behind-the-scenes roles.

Career and collaborations

Sebastian’s career is best understood through his collaborations. He has been associated with projects connected to Timbaland and other Virginia-based musicians, contributing verses or vocal parts on recordings and mixtapes. While he did not achieve the mainstream solo profile of his brother, his work appears across a number of regional releases and collaborative tracks.

Style and themes

His rap delivery fits within a late-1990s/early-2000s hip-hop aesthetic, blending rhythmic cadence with an emphasis on groove and hook-driven sections. Lyrical topics span personal experience, street narratives and braggadocio common to the era’s rap styles, often tailored to complement the producer-driven beats of his collaborators.
