This is an essential package! Whoever put this together obviously knew what they were doing, and all is placed in chronological order. Discs 1-3 are a terrific compilation of material from the MGM years, consisting of commercial recordings of soundtrack materal. If no recording was commercially released, the original soundtrack is used-great for such numbers as "Hoe Down" with Mickey Rooney! But the last disc makes this package essential-here is a pristine soundboard recording of Judy's final performance at the Palace Theater, MYC-2/24/52! She was concluding a 19-week engagement, and the atmosphere is electric. Fantastic stuff!

French pianist Monique Haas recorded the piano works of Debussy and Ravel twice, once in the late '50s and early '60s for Deutsche Grammophon and again in the late '60s and early '70s for Erato. The later recordings are released here in this six disc set from Warner Classics. As on the earlier set, Haas' performances are elegantly stylish, technically impeccable, consummately musical, and quintessentially French. Pick any piece by either composer at random, and you'll see. Try her bright but sensual Suite Bergamasque with its ravishing Clair de lune or her brilliant and visionary Études with their astounding concluding Pour les accords. Or try her recklessly virtuosic Gaspard de la nuit with its frightening Scarbo or her sweetly swaying Valses nobles et sentimentales with its heartrending Épilogue. There are only two meaningful differences between Haas' recordings: in the earlier performance, she is more passionate and impetuous while in the later performances she is more measured and thoughtful.

The Chess Box does not contain all the great music Muddy Waters made. His talent and legacy are too large to be captured in a mere three discs, even one that spans from 1947 to 1972. This means, of course, that his legendary plantation recordings with Alan Lomax are not here, nor is his dynamic late-'70s comeback, Hard Again. But, truth be told, it doesn't feel like they're missing, since Waters' legend was built on the music that he made for Chess, and much of the greatest of that is here. Few box sets have chronicled an artist's best work as effectively as this; even the handful of rare, previously unreleased recordings sit perfectly next to the essential singles (this is particularly true of alternate takes of Fathers and Sons material). Sure, there are great Chess sides that aren't here, but those are great sides that the serious listener and aficionado need to seek out. For everybody else, this is a monumental chronicle of Waters at his best, illustrating his influence while providing rich, endlessly fascinating music.

Completists will be happy to own many of the rarities on this four-disc set, including Stevens's first demo session, an unreleased 1970 duet with Elton John, a cover of Fats Domino's "Blue Monday," and several choice live cuts from the late '70s. And it's nice to have an overview of the artist's entire career–from late '60s pop-star wannabe to '70s folk-rock superstar–in one place. But the difference between early Cat Stevens (despite composing hits for others) and post-Tea for the Tillerman Stevens is substantial. The two follow-up LPs were part of a trilogy of brilliance–both musically and lyrically–and any Stevens collection must start there. Nevertheless, surprises and some gems are to be found throughout all four discs–even his most recent recording (as Yusuf Islam) isn't bad. This box set also offers a choice opportunity to reassess a deserving career. (All royalties go to New York City relief victims and orphans and homeless families in underdeveloped countries.)

Best Of 3CD (The Platinum Collection on the first 2009 issue) is a triple-disc set that contains one disc of Enigma’s greatest hits, one disc of remixes, and one disc of “The Lost Ones,” brief instrumental snippets that were used as source material and ideas for full-length tracks. Naturally, this last disc is what’s interesting for the hardcore fan which, unlike the rest, consists of unreleased material - but even the hardcore may find this slightly ephemeral; after all, these were designed as something like work tapes, not for release. The rest of the set is a good overview of basics, but it’s still unclear exactly who this is for, as this recycles too much for the hardcore, and it’s too lengthy for the casual fan.

Released between 1991 and 2005, the selections in The Warner Recordings encapsulate the period when Pierre-Laurent Aimard was signed to Erato and Teldec, performing mostly 20th-century fare and some music from the 19th century. Aimard is famous for his contributions to the modernist catalog, and his performances of works by Pierre Boulez, Elliott Carter, György Ligeti, and Olivier Messiaen are regarded as scrupulously executed and authoritatively interpreted. Aimard also recorded early 20th century pieces by Charles Ives, Alban Berg, Maurice Ravel, and Claude Debussy, as well as Romantic masterpieces of Beethoven and Liszt. A pianist's pianist, Aimard is well-rounded in his repertoire and a true master of keyboard technique, yet he has received considerably less fanfare than many of his flashier colleagues. Yet connoisseurs of piano recordings know that Aimard is indispensible, especially for his special feeling for French music, and his recordings are important documents that serious students and newcomers should appreciate.

Postcards from Vienna: drawn largely from the supreme players of the Wiener Philharmoniker, collected here are the Decca recordings of Viennese chamber music ensembles, including the New Vienna Octet, Vienna Wind Soloists, Wiener Waldhornverein and Vienna Flute Trio, many making their first international appearance on CD. Led by clarinetist Alfred Boskovsky, the first line-up of the Vienna Octet made it's last recording for Decca in 1972, but Boskovsky was behind the revival of the group's name, having already chosen the young members of the Vienna Philharmonic who would carry on the work of the ensemble and it's traditions of superbly mellifluous, silver-toned playing.
