I think this is where our tastes diverge, Richard.
Shavers was a powerful and exciting mainstream trumpeter, though I'd prefer Eldridge if I had to make a choice.
I listened to Afrique a while ago and thought that Nelson's arrangements didn't suit Basie, who did so well with arrangers like Benny Carter, Quincy, Hefti and Nestico. (Bill Holman was another arranger who wasn't right for Basie IMHO.)
