American blues musician
According to Wikipedia,
Le Moise Roosevelt Graves , credited as Blind Roosevelt Graves, was an American blues guitarist and singer, who recorded both sacred and secular music in the 1920s and 1930s. Biography Roosevelt Graves was born in either Rose Hill or Summerland, Mississippi. On all his recordings, he played with his brother Uaroy Graves , who was also nearly blind and played the tambourine. They were credited as "Blind Roosevelt Graves and Brother". Their first recordings were made in 1929 for Paramount Records. Theirs is the earliest version recorded of "Guitar Boogie", and they exemplified the best in gospel singing with "I'll Be Rested". Blues researcher Gayle Dean Wardlow has suggested that their 1929 recording "Crazy About My Baby" "could be considered the first rock 'n' roll recording."
