Montserrat Caballé emarked in her biography that singing the role of Imogene was tantamount to performing Norma three times. Yet, in this performance, Caballé delivers it with such characteristic ease—navigating each register with seamless fluidity and an astute balance between vocal heft and lyrical delicacy—that any notion of strain feels implausible. Her tone remains luminous and pliant, the dramatic force never overwhelming the line, even in the role’s most impassioned outbursts.

Her husband, Bernabé Martí, assumes the role of Gualtiero. Though his career often stood in the long shadow of his more illustrious partner, he emerges here as a tenor of genuine distinction. His singing reveals both elegance and fervor, with a stylistic acuity well attuned to the demands of bel canto.
