If the angels in heaven really sing, please let them do it like Kelley Nassief. Her voice combines the best of two worlds: It has bel canto size, warmth and height, and yet is svelte, with a youthful sparkle. – So wrote the Leipziger Volkszeitung when Nassief sang Elijah with the Gewandhausorchester and Kurt Masur on the occasion of the sesquicentennial of Mendelssohn’s death.
