It may be just a subway ride away from the biggest Apple, but to some inveterate Manhattanites, an audio show in Brooklyn sounds like it's from another planet. In reality, the third New York Audio Show, which opens to the public on Friday, September 26 at 2pm and continues through Sunday, September 28 at 5pm, takes place at the Marriott at the Brooklyn Bridge, just a short distance across the East River from Manhattan.

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.
