Boy, it's hard to pick two records as the most important two of the twenties, that time when such transformation was going on, but just as hard to come up with a few others to stand along side Albert's two. "West End Blues" is a great soloist tour de force, but Louis' "Sugar Foot Stomp" with Fletcher is a favourite demonstration of the swing music, such an important musical force which he is arguably credited with creating, and "Shanghai Shuffle" goes even further in reducing everything down to the compelling relentless eternal beat. Perish the thought and pour yourself a drink but is it that hard to imagine some fat pants rapper threatening his obsenities to Louis' beautiful solo. Another Fletcher record of great importance must be his "King Porter Stomp" that eventually filtered down to Benny and Berigan to trigger the whole swing era. And "Stampede" with Hawkins' inspired solo that he could seldom rereach with Fletcher that raised the bar for the tenor players and Roy Eldridge also cites as inspiration. The vocalists were so important then too, those that spoke so direct and intimate to the listener seem so important and new, but I can't think of an Ethel Waters or Hanshaw record to stand out as 'most important', maybe you have to think of sum total rather than an individual record. Maybe Bessie's "St Louis Blues" for its jazz blues ballad tone. And being that dancing is the hallmark of the century, is there one record more than any other, neither of which would be "Singin" or West End', that summoned the people to join in and shake their booty. Maybe even Whiteman, I ain't got a clue.
