Benjamin Clementine, Queen Elizabeth Hall, Southbank Centre, review: Every word is performed with certainty and purpose

Despite repeat comparisons to Nina Simone from critics, it’s hard to pin London-born, Paris-dwelling Benjamin Clementine down. His voice certainly has the richness of Simone, but his style of performing and theatrical flair is entirely his own. His song Adios, from album At Least For Now, for example, would not be out of place on Broadway.
