"Music has the potential to unite people from varied backgrounds and cut across class barriers," says Taru Dalmia, also known as reggae artist Delhi Sultanate and the lead singer of ska band The Ska Vengers. It's this thought that has made him start the Reggae Sound System project. The idea is to build a travelling sound system that can be put up anywhere, so that music can be heard and felt — thanks to the bass-heavy music — as an open community.
