Watching the Ghanaian-born drummer Paa Kow (pron PAH-Koh) perform with his Afro-Fusion Orchestra last Thursday evening, 7 October, at the Redstone Room in Davenport, one wondered briefly if he functions on pure enthusiasm. His fellow-musicians were alert to every key- and tempo-change, and Paa Kow often surprised his audience by leading them down different melodic paths when a song seemed instead to signal its conclusion.
