This is a wonderful collection. It's surprising that RCA/Sony hasn't done something like the 10 CD set they did for Jussi Bjoerling, but this more than makes up for it. (Although it's not too late RCA!)The description 'Early Performances' is both accurate and inaccurate. The Colin Davis and Alceo Galliera recordings are there as are highlights from the rare Don Giovanni from the Hans Rosbaud recording with Antonio Campo as Don Giovanni, highlights from La Figlia del Reggimento, excerpts from the Callas Boheme, Respighi's La Fiamma. the Karajan Falstaff, the Sawallisch Capriccio, the Giulini Nozze di Figaro, the Bartoletti Sonnambula, and the complete Galuppi I Filosofo di Campagna. What's missing that I wish were here is the Pergolesi La Serva Padrona which I've copied from the old LP.Also included are later recordings of highlights from the RCA Traviata and Madama Butterfly.I've only listened to the first CD of the Don Giovanni highlights, so I can't comment on the rest of the set, but the sound seems to be very good.
