I want to make the case for a sound being dull.
Mohammad Omar was one of the few players of the rabab lute to gain any fame outside of his native Afghanistan. His instrument has an amazing tone: while it is dull, it's also earthy and complex and often quite distant. It's chewy. Here he is in concert from 1974 with a very young Zakir Hussain who still manages to complement him ideally. Hussain's tabla is crisp and sharp and he wasn't afraid of engaging the old master in some fearsome musical duelling. This is a rare chance to hear this ancient and very engaging musical tradition.
