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