Personnel: Big Bill Broonzy (vocals, guitar); Washboard Sam (vocals); Black Bob, Blind John Davis (piano).

1937 was a busy year for Big Bill Broonzy, who was turning 44. A greatly in-demand blues guitarist in Chicago, Broonzy was also an underrated singer and a major solo artist. This CD from the Austrian Document label (the sixth of 11 that trace his entire prewar recording career) includes 26 selections with plenty of alternate takes and nine previously unreleased performances. Broonzy is joined by either Black Bob, Leeford or Aletha Robinson or Joshua Altheimer on piano (Blind John Davis joins up for the final session), and sometimes bassist Bill Settles, drummer Fred Williams, unidentified players and (on three occasions) trumpeter Punch Miller. Although not quite essential, this CD will be desired by Broonzy's greatest fans, along with all of the releases in this very valuable series. Among the more notable selections are "Mean Old World," "Down in the Alley," "Louise, Louise Blues" and "It's Too Late Now." ~ Scott Yanow
