I recently revisited the works on Renzo Piano and recall an interview he did with John Tusa for BBC Radio 3 which I discovered a few years ago.
The list of interviewees on The John Tusa Interviews is impressive and they are all fascinating to hear (or to read as the transcriptions of the interviews are published) online. It may be tough going to hear/read them all at once and definitely not a good idea to do so, but it is good to come back to these interviews and tackle one by one, as I have been doing for a while.
Since this is a composer’s blog after all, I might as well mention the five composers on the list (at the time of writing) – Louis Andriessen, Harrison Birtwistle, Elliott Carter, Heiner Goebbels and György Ligeti.
