Killer unissued rockin' blues cuts x2 here as we unleash the hot, hot alternate take of Little Walter's 'Mean Old Frisco' on 45 for the first time. Whilst the session dates back to 1959, Chess waited six years to release the song, and even then, we feel that they chose the wrong take as this groovier, more driving rendition is surely superior - certainly it seems to work the dance floor better if our recent experiments with the Test Pressing prove representative.
