Mitchell’s Christian Singers, Complete Recorded Works in Chronological Order, Vol. 1 (1934-1936) (Document). The rough-hewn, sometimes startlingly dissonant a cappella harmonies of this vocal quartet, which traveled from North Carolina to Carnegie Hall in 1939 to sing at John Hammond’s first From Spirituals to Swing concert and subsequently got written up in Time, have since caught the ears of everyone from Bob Crosby to Maria Muldaur. The first volume of Document’s comprehensive reissue of the group’s 78 recordings contains its best-known side, “Traveling Shoes,” plus plenty of other gospel songs that swing and shout like nobody’s business (TT).
