ReviewA good quality recording of a Maria Callas performance from 1957, showcasing her voice in its prime. The voice has a silvery quality, with beautifully sung scales, staccati, and top notes. The live recording reveals her ability to fill a theatre with her special sound quality, and to dominate a performance with the Callas magic. The supporting cast is also fine. One might hope that someday the sometimes intrusive audience sounds heard during musical highlights could be reduced or eliminated from the soundtrack. The role of Amina in La Sonnambula is the kind of coloratura vehicle that helped propel Callas to fame, and the kind of singing often omitted in more recent compilation recordings that focus on her later recordings of music in a later verismo style rather than the florid (though melodious) one heard here.
