Francesco Biraghi wrote a rave review in the Italian guitar magazine, Il Fronimo, of the “Letter to the World” album of Leisner vocal chamber music. Amongst other things, he wrote: “Leisner conquers us not only with the beauty of the music, but particularly with the coherence of musical expression in relation to the lyrics…A recording that deserves the highest praise. Some passages of great intensity will remain in our emotional memory for a long time.”
