Sorry to hear, I appreciate his work with Fleetwood Mac, particularly during the era of Then Play On thru Future Games. Fluid tactile & nimble he expressed a focused melodic tone tempering & coloring the fervid maelstrom his fellow six-stringers conjured with abandon.
That's essentially all I know of DK, but for me, enough to rate him as a true Rock & Roller. He held his own up against Peter Green & Jeremy Spencer, no small challenge considering him being the teenage aspirant he was at the time.
