A true Callas cornucopia, this 70-CD set gathers together everything Maria Callas ever recorded in the studio. That's 26 complete operas (four of which are studio repeats), plus the complete studio recitals made during the legendary soprano's recording career, which lasted from 1949-69. The bonus CD-ROM contains libretti and translations in English, French and German, plus a Callas photo library, while remastered treats include Callas's first recital recording, originally made for the Fonit-Cetra label and featuring arias by Wagner and Bellini. – Barnes & Noble
This reissue box collects the entire cycle of Mozart keyboard sonatas, plus single-movement works, recorded by Austrian pianist Paul Badura-Skoda on a 1790 Schantz fortepiano that he himself owns. The six CDs included were originally recorded between 1978 and 1990 for a group of related French labels; the budget-price reissue on Naïve is a bit atypical for that label, which has specialized in innovative and lavishly designed full-priced releases. Online retail presentations may not make clear that they are fortepiano recordings, recordings made on a keyboard instrument probably very much like one Mozart would have played himself.
The contents of the EMI box are too numerous to list but all the sonatas, variations, and most short pieces are here: absent is the London Sketchbook, which is trite juvenalia.
