Above: one of my longtime favorites, mezzo-soprano Bianca Berini
I vividly recall watching this performance of the Verdi REQUIEM when it was telecast in 1980 as part of the Live from Lincoln Center series. The soloists are Montserrat Caballe, Bianca Berini, Placido Domingo, and Paul Plishka, with Zubin Mehta conducting the New York Philharmonic and the Westminster Choir.
Watch and listen here.
