Riley B. King (September 16, 1925 – May 14, 2015), known professionally as B. B. King, was an American blues guitarist, singer, songwriter, and record producer. He introduced a sophisticated style of soloing based on fluid string bending, shimmering vibrato, and staccato picking that influenced many later electric guitar blues players. AllMusic recognized King as "the single most important electric guitarist of the last half of the 20th century".

He was inducted into the Rock and Roll Hall of Fame in 1987 and is one of the most influential blues musicians of all time, earning the nickname "The King of the Blues", and is referred to as one of the "Three Kings of the Blues Guitar" (along with Albert King and Freddie King, none of whom are related). King performed tirelessly throughout his musical career, appearing on average at more than 200 concerts a year into his 70s. In 1956 alone, he appeared at 342 shows.
