Yes - I was impressed by the band's playing on the Fleischmann broadcasts - it ought to have been great given the personnel, but I was still underwhelmed by the charts. I'm not unmindful of Allen's point about the context but I can't accept that Louis was best-served by cheesy arrangements. We can say "Gosh he's great, in spite of etc." Or "rises above" ad infinitum, but whichever way you look at it, they're still antiquated, lumpen and fundamentally square compared to what else was going on in, say, 1938. It is, of course a great tribute to Louis that he was able to make so many silk purses out of sows' ears and his playing is generally sublime whatever the vehicle. I think, though, that his playing at NY Town Hall in 1947, albeith in a totally improvised setting, gives a hint of the level of creativity he might have achieved with the big band via more challenging material and arrangements.
Maybe Louis would have been better served by Irving Mills....
