Slim Harpo, born James Isaac Moore, was an influential American blues musician active during the mid-20th century. He was renowned for his mastery of the harmonica, which characterized his signature sound, and his laid-back, rhythmic style that set him apart in the blues genre. His most notable track, "I'm a King Bee" (1957), significantly impacted the British blues boom and influenced many rock artists. Harpo's contribution to blues music, particularly the development of the 'swamp blues' subgenre, cements his place in music history.
