Riley B. King (born September 16, 1925), known by the stage name B.B. King, is an American blues musician, singer, songwriter, and guitarist.

Rolling Stone magazine ranked him at No. 6 on its 2011 list of the 100 greatest guitarists of all time (previously ranked No. 3 in the 2003 edition of the same list), and he was ranked No. 17 in Gibson's "Top 50 Guitarists of All Time". According to Edward M. Komara, King "introduced a sophisticated style of soloing based on fluid string bending and shimmering vibrato that would influence virtually every electric blues guitarist that followed." King was inducted into the Rock and Roll Hall of Fame in 1987. He is considered one of the most influential blues musicians of all time, earning the nickname "The King of Blues", and one of the "Three Kings of the Blues Guitar" (along with Albert King and Freddie King). King is also known for performing tirelessly throughout his musical career, appearing at 250-300 concerts per year until his seventies. In 1956 it was noted that he appeared at 342 shows. King continues to appear at 100 shows a year.
