Lotte Betts-Dean’s performance was powerful and lyrical, exhibiting a masterly control of both vocal range and colour. Shifting timbre from ghostly thin incanting to the wild throes of a full-bodied dramatic mezzo, Betts-Dean’s devoted performance captured all the ecstasy and drama of Messiaen’s poetry with a mature artistry.

Betts-Dean gave a mesmerising performance...
we were engrossed in not just what she was opining, but her movements and her facial contortions. At times she looked as though she was about to leap into the audience, so manic did she appear.
