Simon Callow at the NYRB:
When I was growing up in Britain in the 1950s and 1960s, Paul Robeson was much in evidence, on records, on the radio, on television. His name was haloed with the sort of respect accorded to few performers. The astonishing voice that, like the Mississippi in the most famous number in his repertory, just kept rolling along, seemed to carry within it an inherent sense of truth. There was no artifice; there were no vocal tricks; nothing came between the listener and the song. It commanded effortless attention; perfectly focused, it came from a very deep place, not just in the larynx, but in the experience of what it is to be human. In this, Robeson resembled the English contralto Kathleen Ferrier: both seemed less trained musicians than natural phenomena.
The spirituals Robeson had been instrumental in discovering for a wider audience were not simply communal songs of love and life and death but the urgent cries of a captive people yearning for a better, a juster life.
