Magos Herrera is a smoky jazz singer from Mexico, and producer Javier Limon is quite taken with her. So much so that he's touring with her. And this is the only London date. So, if you like things smooth, emotional, and intense, you can't do better than Magos Herrera. The Union Chapel is a fittingly beautiful backdrop for such gorgeous music. General admission. Under 16s must be accompanied by an adult.
