Der Ring des Nibelungen

"Nearly perfect"

The Erda of Cindy Sadler was nearly perfect.

"Knocked 'em dead"

Cindy Sadler knocked ‘em dead with Erda’s last-minute, nearly deus-ex-machina appearance.
Kenneth LaFave

"Opulent mezzo"

Cindy Sadler displayed an opulent mezzo as the somnolent Erda.
Dorothy Stowe

"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.
Paul Sweitzer

"Rich-voiced... true frisson"

The great scene with Erda in Act III of Siegfried … is always thrilling theater, and with (Edward) Crafts … and contralto Cindy Sadler, a rich-voiced, pungent Earth Goddess, true frisson was achieved.
JA Van Sant
