Der Ring des Nibelungen

"Nearly perfect"

“The Erda of Cindy Sadler was nearly perfect.”
— Opernwelt

"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
