After a chance encounter with a colleague who had studied Indian music, Nancy Lesh decided to spend a summer holiday in India. Having been trained in Western classical music for 12 years, she had assumed that Indian music was “less refined”—but she fell deeply for Hindustani music, and began training in dhrupad, transferring the vocal style to her cello.
Eventually she began to study with the renowned Zia Mohiuddin Dagar, modeling her playing on the rudra vīṇā, the only instrument on which dhrupad is played. “Sixteen years later,” she says, I realize that this music is just beginning to mature within me.”
This according to “Hindustani music on cello” by S. Sankaranarayanan (Sruti 179 [August 1999] pp. 39–41). Below, a performance from 2013.
