At age 13, Shivkumar Sharma’s father, the singer Uma Dutt Sharma, decided that his son should become the first musician to perform Hindustani (North Indian) classical music on the santoor, a hundred-stringed hammered dulcimer played with a pair of light walnut-wood mallets. Sharma’s brilliance on the instrument—he translated his vocal and tabla training into lightning-fast runs, liquid glissandi, and an emotional melodiousness—made 1967’s divine Call of the Valley one of the highest-selling Indian albums to date and landed him a session on George Harrison’s Wonderwall soundtrack. Now 75, Sharma has been collaborating with peerless tabla master Zakir Hussain since 1966, and their infrequent local appearances are don’t-miss events of virtually guaranteed musical transcendence for 
appreciative East Coast raga cognoscenti.
