It is known that she traveled by train to Memphis, Tennessee, in 1928, alongside Bessie Tucker and Charlie Kyle, with the intention of recording for Victor.
[3] Memphis was the location of the recording studio nearest to her home, which is generally agreed to have been in Texas.
[2] The pianist K. D. Johnson, born in Dallas, Texas, accompanied both Mack and Tucker on their recordings,[2] which took place on 29 and 30 August 1928.
