Someone said in another thread something along the lines that the thirties marked a period where many artists churned out a repetitive and unvarying series of releases... but maybe this story is slightly inaccurate - I can't help noticing that to my ears, many (most?) blues artists of the twenties become tedious over twenty songs on the trot - even highly regarded players like, say, Clifford Gibson or Sam Collins or Frank Stokes. How many blues artists had a genuine repertoire of more than 10 songs? Not many I think. Of course it is true though that in the thirties they tended to go on for longer, I mean, Peetie Wheatstraw even got bored of that tune himself and dropped the playing altogether.
