I was aware of him but not much more than as a name, so looked him up. Interesting guy, as you say. As well as the white-guy-popular-with-black listeners thing, maybe he fell down one of the cracks between the various pigeonholes we like to put musicians in.
Look forward to the follow up - I won't spoil it by mentioning any of his discoveries but like you say he could spot talent when he heard it. Found you just today (from your #morgenseiten Elvis post, following a lead from @shortcut) and will be looking out for more. Thanks.
