Anthony B (born March 31, 1976) is the stage name of Jamaican musician Keith Blair.

Blair grew up in rural Clarks Town of the northwestern parish of Trelawny. His deeply religious family life (his mother was a Seventh-day Adventist and his grandmother a Revivalist) imbued him with a profound spirituality. During his youth, his favorite singers were Bob Marley, Peter Tosh, and Bunny Wailer, musicians who strongly influenced his own style. Peter Tosh's influence can definitely be heard in Anthony B's vocal delivery and revolutionary stance.

Anthony B adopted Rastafarian beliefs as a teenager, a decision which was not well-received by his family. The stubborn and determined Anthony B refused to give up his new religion and his dreadlocks and moved to the home of his aunt and uncle in the Kingston suburb of Portmore. While attending high school, Anthony B debuted as a deejay for the local soundsystem, Shaggy Hi-Power. In 1988, he befriended reggae artists such as Determine, Mega Banton, Ricky General and Terror Fabulous.

At this point in the reggae industry singing "slack" songs about women was the popular thing to do. Anthony B did not believe in degrading women and chose to pen politically-slanted songs rather than so-called "gyal chunes." He hooked up with Little Devon the Half Pint sound-a-like singer he made his debut single "The Living is Hard" on the Wizard Label in 1993. Anthony B tried many different producers but found that none of them fit his style of music. Finally, when Anthony B teamed up with Richard "Bello" Bell he produced hits such as "Fire Pon Rome", "Raid Di Barn", "Rumour", and "Repentance Time." Anthony B's 1996 debut album "Real Revolutionary" was highly acclaimed in the reggae community. In late 1997, Anthony B released "Universal Struggle" which showed that Anthony B had a consistent, high-calibre talent. Anthony B has released a large number of albums since that time including 1999's Seven Seals and 2005's Black Star which featured collaborations with such artists as Wyclef Jean.

Anthony B is a member of the Bobo Ashanti branch of the Rastafarian movement. "Bobo Dreads" as they are known are recognizable by their long robes and turbans. The strong Afrocentric pride and the other Rastafarian beliefs (or overstandings as Rastafarians prefer to call them) which Anthony B holds are reflected in his songs. Anthony B tours extensively in Europe and North America and is known for his fiery high-energy performances.
