Move over John, George, Ringo, and Paul. There's another remastering that's come on the scene, and it's every bit as important as the Beatles Mono Edition. It's Warner Classics' high-resolution, 24/96 digital remastering of soprano Maria Callas' entire studio-sourced discography. Consisting of arias, recitals and complete operas recorded 1949–1969, the remasterings reach the international public on September 22, and US music lovers on September 23. Their sound, whether in the 69-CD box set of her entire studio recordings, or HDtracks' 24/96 downloads of its individual components, is revelatory.
