"Magnificent mezzo... unbelievably rich"

For two ‘Ring’ seasons in Flagstaff, Sadler has been a vocal and dramatic mainstay of Arizona Opera. The mezzo appears in all four of the Ring dramas … she brings to each a magnificent mezzo voice that is big, well-controlled, and always, always, unbelievably rich throughout its range. Her Erda … was an all-around masterpiece of operatic declamation.
