By September, Leonard Chess had invested in the young record company.

[1] By early 1950, Leonard and his brother Phil had become the sole owners, and in June of that year they changed the company's name from Aristocrat to Chess Records.

On August 27, 1947, Muddy Waters made his first recordings for Aristocrat, which produced the single "Gypsy Woman" b/w "Little Anna Mae".

Backing him were bassist Ernest "Big" Crawford and pianist Sunnyland Slim.

[3] After a second session in December 1947, Aristocrat released "I Can't Be Satisfied" b/w "Feel Like Goin' Home," which became a minor hit.
