Sudha Raghunathan is one of the leading Karnatak vocalists in India. She is an A-grade artist under All India Radio's rating system. She was trained by Smt Choodamani, B.V. Lakshmanan, and M.L. Vasanthakumari. She has toured extensively throughout Europe, and somewhat within the United States as well, but the bulk of her performance time goes into radio, television, and album recordings within India. ~ Adam Greenberg
