Throughout the 1990's as well as the 1980's, 1970's, 1960's and 1950's, there has been only one King of the Blues - Riley B. King, affectionately known as B.B. King. Since B.B. started recording in the late 1940's, he has released over 60 albums many of them considered blues classics. Over the years, B.B. has developed one of the world's most readily identified guitar styles. He borrowed from Lonnie Johnson, Blind Lemon Jefferson, T-Bone Walker and others, integrating his precise vocal like string bends and his left hand vibrato, both of which have become indispensable components of rock guitarist's vocabulary. B.B. has mixed traditional blues, jazz, swing, mainstream pop and jump into a unique sound. His singing is richly melodic, both vocally and in the "singing" that comes from his guitar. In B.B's words, "When I sing, I play in my mind; the minute I stop singing orally, I start to sing by playing Lucille".
