 Arnold embarked on his 11th solo album "Sonnet 155" by writing over 30 letters to Shakespearean actors, including Ian McKellen, Derek Jacobi, Pete Postlethwaite, Richard Briers, Janet Suzman and Emma Thompson in the hope that they would provide further inspiration and help turn ideas into songs.The responses he received became the basis for many of Arnold's songs.The album is a rock/classical crossover all driven by Shakespearean themes.
