Thanks for trying to read the article, although it's in German language. Maybe the video has some geo-restrictions and is only viewable in Germany. I'm sorry for that.
Also thanks for pointing me to the Bengali poet, I listen to some Indian music sometimes. Ravi Shankar was a real inspiration.
thats true... he is a legend. and RABINDRANATH is an indian poet but majority of his creation in bangla. i think you will enjoy him also.
