“Xavier is a wonderful listener, and his work is deeply collaborative.
He is able to calmly guide a student through a text or an aria, down to its most elemental, direct, true, and profound expression.
I was amazed at how Xavier, though never interfering with any singer's technique, was able to help every singer also vocally perform their pieces better in an utterly transformative, connecting and truly touching performance.
His methods are easily accessible, definitely adaptable for my self study and especially helpful for audition repertoire.”
