cecilia has been singing at the salzburg whitsun festival in austria where she is artistic director. as live performances begin again, i talk to her in salzburg via video link in london and ask her what it's like to be back before an audience. i mean, it's fantastic. it really is such a joy because last year we had to cancel the festival and now it is great. we really need that because it was such a difficult time, yes, a tragic time, i have to say. so, happy to be back, yes. now, when you were a young girl you wanted to become a flamenco dancer. a little bit! yes! but it was your mother, who was herself a soprano, who recognised that you had real vocal talent, and she became your voice teacher. what was it like to be taught by your own mother? to study with my mother was hard.
