Rachele made her Opéra de Lille debut to great acclaim in Donizetti's Lucia di Lammermoor. Audrey Chaix of Toute la culture writes:
'Rachele Gilmore magnificently interprets the beautiful Lucia. Between strength and fragility, she plays a young woman with accuracy, oscillating between rage of the woman scorned and manipulated by all these men who play it, the despair of the wounded lover, and the loyalty of the honorable sister… Gilmore's soprano voice is just perfect, from the first act where it has established itself as an excellent Lucia, but especially in the last part: the famous air of madness is a real tour de force, and the public of the Lille Opera House holds its breath with passion before releasing bursts of applause amazed.'
And Graeme Feggetter of Opera says:
Rachele Gilmore’s Lucia was a small, vulnerable figure with a gloriously accurate voice.”
