Luther Johnson (born Lucious Brinson, August 30, 1934 or 1941 – March 18, 1976), sometimes credited with the sobriquets “Georgia Boy”, “Snake”, or “Snake Boy”, was an American Chicago blues and electric blues guitarist, singer and songwriter.

AllMusic journalist Ron Wynn stated, “Johnson’s own inimitable vocals, raspy lines and tart guitar eventually create his own aura… a good, occasionally outstanding blues artist.” He is not to be confused with Luther “Guitar Junior” Johnson, nor Luther “Houserocker” Johnson, from Atlanta, Georgia.

He was born in Davisboro, Georgia. Sources give different years of birth, ranging from 1934 to 1941 (according to his headstone), though 1939 has also been published. He was raised on a farm and taught himself to play guitar.

After completing his service in the US Army, Johnson played guitar with the Milwaukee Supreme Angels, a local gospel group in Milwaukee, Wisconsin. However, he gravitated towards blues and formed his own trio in Milwaukee. He relocated to Chicago, Illinois, in the early 1960s. He backed Elmore James prior to his James’s death in 1963, and joined Muddy Waters‘ backing band in 1966. Johnson worked with various musicians during this period, including Chicago Bob Nelson. He recorded his debut album, Come On Home, in 1968, with Muddy Waters’ band.
