Here are some links to news reports. Not too many mentions of a musician's right to earn a living.
I'd also like to point out the description of the Facebook group created for the protest. Again, no mention of a musician's fundamental right to be allowed to earn a dignified living.
"Citizens..its about time we come together..and protest the right to our freedom..Freedom is our birth right! Lets have them lift the mindless ban on live music bands..the 11:30pm curfew ..lets have our nightlife back..lets get Bangalore back..lets make the right noise..not a commotion.. Who the people??? We the People!!! And we can change it ! Come together everyone!!!"
