Several South Asian bands and artists have put out music that protests social and political injustice. Almost the entire output of bands such as the Asian Dub Foundation or Fun-Da-Mental is comprised of this type of music. Additionally, individual artists such as Karsh Kale and Haroon have put out songs that are critical of the ills in society. Ghazal singers have also recorded similar pieces, notable Iqbal Bano's rendering of Faiz Ahmad Faiz's "Hum daikhain gey".
I'd like to build a list of protest music from South Asia and the South Asian diaspora. If you know of this type of music, please post a comment. If you can supply full discographic information, that would be great.
Thanks for your help.
