Logo & Branding for fundraising/charity initiative: "Sing Against Slavery"

This is what Sing Against Slavery was looking for in their logo design

We need a recognisable and clever logo for a new project that uses amateur singers and arranges concerts to raise awareness of Human Trafficking/Modern Day Slavery and to raise funds for the fight against Human Trafficking/Modern Day Slavery. Open to ideas. This is a seriously good cause that will help people who find themselves as modern day slaves in 2014! So please do give us your very best and cleverest work. We are open to ideas - and happy to progress and grow ideas in two-way-feedback.

Thank You!!

Themes to convey: Impactive, Serious, Gravity, Humanitarian, Passion, Entertainment, Healing, Freedom, Purity, Compassion.
