There is a beggar in Madurai who looks and sounds very similar. Everyday evening he comes to the street near the rly station where all the lodges are present, sets up a mike sits down and sings in the most soulful voice, tapping on a kanjeera, till late upto midnight. Authentic Tamil "blues" without imitating any American music.
These people have more soul in their music than most mainstream artists.
