Pandit Ravi Shankar was just one of those masters from Indian subcontinent who happened to get famous and so comes to attention.
Back here in India, such people are quite common[Not to say they are all over the place, but you just don't hear about many of them]. Most of them just don't come up because of lack of encouragement, and proper ways of monetizing their art.
Just to tell you. Back in the past when I was in school. We would practice for hours singing devotional songs in Carnatic music. There was once a inter school competition, where you could sing in any genre you want. Our opposition school was totally convinced our 'old music' didn't stand a chance. To add to our bad luck, they had a complete band that could play with piano, guitar and band. We had none of that. Despite that, our singing was so damn awesome- we didn't just win. But looked something like 100 times more awesome than they were. In fact when the results were announced the judges said, they hadn't heard anything like that before. Coming from average middle class background, I couldn't even convince my parents to come and watch how I sang. No photographs were taken, none of it was recorded. On top of it my parents thought singing was an utter waste of time, and If I get too much into it I wouldn't study well- And so won't be able to get a good job. I wasn't able to rekindle my passion for music until later after I started earning.
There isn't a shortage of how many such competitions I participated in.
You will not believe how much of such talent goes wasted here. And even talent that some how continues into a full practice never gets any attention. Artists often live in poverty, and perform for peanuts. What that basically means is even talented kids don't want to take it up as a full time profession.
