Nice to hear that you're interested in Asian music
Well, I sing actually
. But I sort of know the basics of playing violin and to a lesser extent veena. Not sitar though.
Depends on which sort of music you like
If you're talking about sitar, I'd recommend the artistes Ravi Shankar and his daughter, Anoushika Shankar. Just my opinion.
There is basically two main streams of classical music- Hindustani and Carnatic. So if you can tell me which you're interested in, I can maybe be more specific.
