Shankar was one of the first Indian classical musicians to take the sitar beyond the country's borders, touring Europe and the U.S. in the 1950s for "occasionally puzzled" audiences, according to an early Time magazine review.

Brian Jones of the Rolling Stones and George Harrison of the Beatles started playing the sitar in pop songs, and Shankar was a star on stage at Woodstock, the Monterey Pop Festival, and the Concert for Bangladesh.
