When Algebra Blessett sings, everyone stops and listens. It's not just her range that's incredible; it's those smooth as silk vocals that could charm the most callous of hearts. Algebra served as a backing singer for Monica and Bilal before striking out with her debut album Purpose, which lingered in the US Billboard R&B chart for 14 weeks. With support from Sulpacio Jones, Gwendolyn Collins, Dolla Lova and Imaani, it all adds up to a spectacular night of soul. You do the maths. Over 18s only.
