Sippie Wallace was one of the great blues singers of the 1920s. Although she occasionally sang non-blues material on records, the blues was where her powerful voice sounded best. Document, on two CDs, has released all of her recordings prior to 1958. The first disc starts out with impressive performances on the hits "Up the Country Blues" and "Shorty George Blues," which find Sippie backed by Eddie Heywood, Sr.'s fluid piano (one of his best records). Wallace is heard accompanied by Clarence Williams' more basic piano during 1924-25 and with bands that include Louis Armstrong (very much in the background on two songs), Sidney Bechet, cornetist King Oliver (for three songs), other Williams associates of the period, plus her young brother, pianist Hersal Thomas. Among the more notable selections are "Mama's Gone, Goodbye," "Leavin' Me Daddy Is Hard to Do," "Baby, I Can't Use You No More," "Walkin' Talkin' Blues," "I'm So Glad I'm Brownskin" and "Devil Dance Blues." Although the second Document volume gets the edge (better recording quality and some exciting contributions by Louis Armstrong), the first CD is well worth getting too by vintage blues collectors. Most of these performances have been difficult to find for decades.
