Welcome to the Message Forum! You can write here messages, questions, comments etc. on Karita Mattila. I will try to find answers as soon as possible.
A coincidence - I saw the Met's televised "Tosca", with Matila and a rather loud Alvarez last night, while remembering a recent hearing of the monophonic recording with Callas and De Sabata conducting. For my comment, see my "Tosca" posting.
