Albert Nelson (April 25, 1923 – December 21, 1992), known by his stage name Albert King, was an American blues guitarist and singer whose playing influenced many other blues guitarists. He is perhaps best known for the popular and influential album Born Under a Bad Sign (1967) and its title track. He is one of the three performers (together with B. B. King and Freddie King) known as the "Kings of the Blues. "He was also known as "The Velvet Bulldozer" because of his smooth singing and large size—he stood taller than average, with sources reporting 6 ft 4 in (1.93 m) or 6 ft 7 in (2.01 m), and weighed 250 lb (110 kg)—and also because he drove a bulldozer in one of his day jobs early in his career.
