Sonya Yoncheva, the Bulgarian soprano who will star in Purcell's opera Dido and Aeneas at the National Auditorium in Madrid and Oviedo this October, was the guest this Tuesday on David Broncano's La Revuelta. In addition, the programme included a section by Yunez Chaib, and she issued an authorisation for some university students to be absent from class, and a certificate of disability.
