A grand panoramic sweep of Wagner's illustrious life and prolific oeuvre, beginning with the tumultuous prelude to the 1848 Revolution, continuing through his exile in the picturesque Swiss Alps, to the remarkable rescue by the deeply enchanted King Ludwig II of Bavaria, and culminating in the resounding triumph at the iconic Bayreuth Festival. Wagner's audacious musical and political theories, his fervent German nationalism, and his complex attitudes towards anti-Semitism are all vividly portrayed within the intricate tapestry of his life and the era that shaped him.
