Although the caste system was banned by the Indian constitution, caste-based discrimination has persisted and evolved into many sub-castes, especially in villages. Casteless Collective, a brainchild of Indian film director Pa Ranjith, are using music to shake up this notorious system of stratified social class. The band sings about manual scavenging, LGBTQ issues, violence against women, corruption, land grabs and voting rights. The songs however have elements of intrigue, humour, melancholy, playfulness and incredulousness tinged with sarcasm. Guardian presents the brave collective.
