Riley is the son of veteran singer Jimmy Riley and nurse Lavern Tatham. He was born in Brooklyn and grew up in South Florida. He began his musical career as a deejay working with Busta Rhymes, taking his birth sign as his stage name at his mother's suggestion (the spelling later changed from Taurus to Tarrus), and recorded his first singles for his father's Love & Promotion label. He was guided in his early career by Dean Fraser, who also performs in his band and produces much of Riley's work. Riley has released three albums, Challenges (2004), Parables (2006), and Contagious (2009). Contagious features guest appearances from Damian Marley, Vybz Kartel, Etana, Konshens, Demarco and Duane Stephenson. His commercial breakthrough came in 2006 with the Parables album and the Jamaican number one single "She's Royal".
Riley was awarded the Reggae Runnins Caribbean Heritage Award at the 2009 HOT 105 FM Caribbean-American Heritage Awards. He was nominated in the Best Reggae category of the 2009 MOBO Awards.
Tarrus has consistently been awarded for his contribution to the industry and for touching the people. “From I released Parables, I’ve been getting ‘Best Singer of the Year” or ‘Best Song of the Year’ awards, both locally and internationally. But to be honest, the best award I receive constantly is from the people themselves – when I can look in their faces and see the impression my music has made – that is the Best award I can ever get,” he comments genuinely. Nonetheless, Tarrus is the proud holder of CVM’s 15th Anniversary Award, held in February 2009, for the ‘Most Admired Song in the Past 15 Years’ for the hit, “She’s Royal”. “That award really means a lot to me because it was chosen by the people in the streets,” he shared keenly.
