"There's a unique component of music that is different from, the written pamphlet or a speech. There's something, when you get the right combination of rhythm, melody and the right lyrical couplet, that feels like truth in the reptilian brain. There's something hardwired in our D.N.A.. And when you get a large group of people singing together in solidarity, it's something that, in my experience, and I've played countless demonstrations and protests through the years, it's something that can really help a struggle."
