Twickenham alumni, Anna Calvi is an incredible live performer and writer of intense, uplifting music that puts you in mind of Edith Piaf and the great soul singers of the fifties and sixties. There are classical elements to her sound but it’s really the raw intensity that comes across in her performances, cracking the hearts of even the most jaded indie musos with her operatic voice and formidable guitar playing. If you get a chance to see her live, take it.
