Opera singer Peter Brathwaite shares his passion for five very different singers whose voices, artistry and lives inspire and move him, and whose stories he needs to tell.

Peter explains why Bentley's untrained but completely committed voice has always captivated him, a fellow Lancastrian, and uncovers the profound effect Bentley's work has had on his own career.
