The greatest of Mozart's wind serenades and the toughest of Alban Berg's major works might seem an unlikely pairing, but in an interview included with the sleeve notes for this release, Pierre Boulez points up their similarities. Both works are scored for an ensemble of 13 wind instruments (with solo violin and piano as well in the Berg) and both include large-scale variations as one of their movements - and Boulez makes the comparisons plausible enough in these lucid performances. It's rare to hear him conducting Mozart, too, and if the performance is a little brisker and more strait-laced than ideal, the EIC's phrasing is a model of clarity and good taste. It's the performance of the Berg, though, that makes this such an important issue; both soloists, Mitsuko Uchida and Christian Tetzlaff, are perfectly attuned to Boulez's approach - they have given a number of performances of the Chamber Concerto before - and the combination of accuracy and textural clarity with the highly wrought expressiveness that is the essence of Berg's music is perfectly caught.

Maria João Pires “shapes and colours every phrase, and with immaculate taste, and she makes sure the phrases end as eloquently as they begin,” wrote Gramophone in 1974. “She conveys not just the details but the relevance of every note to the whole … Best of all, she communicates everything she has discovered about the music, and it is worth having.” This Portuguese pupil of Wilhelm Kempff, Pires was one of the artists who defined the Erato label in the 1970s and 1980s. This 5-CD box gathers together the recordings she made over the period from 1976 to 1985 and it reflects the consistent focus of her repertoire, with its special emphasis on Austro-German composers of the Classical and early-Romantic periods. Embracing solo works, piano duets and concertos, it contains works by Mozart, Schumann, Beethoven, but also by Bach and Chopin.

This compilation covers 20 years of live recordings made by conductor Yevgeny Mravinsky and the then-named Leningrad Philharmonic Orchestra for Erato. Mravinsky led that orchestra for nearly 50 years, from 1938 until his death. His last recording was that of Shostakovich's Symphony No. 12, made in 1984, found on Disc 3 here. His interpretations of Shostakovich and Tchaikovsky were highly regarded, so it's not surprising that several of their symphonies are here. There are also symphonies by Mozart and Beethoven in this set; tone poems by Tchaikovsky and Mussorgsky; and orchestral excerpts from operas by Wagner, Glinka, and Glazunov. The final disc contains a rare recording of a rehearsal led by Mravinsky, something few outsiders were ever allowed to witness. Even though he was an elder statesman of Russian music at the time of these recordings, there is still precision and energy in his interpretations.

Radu Lupu and Murray Perahia should have recorded all of Mozart's piano music for four hands, which includes several neglected masterpieces. This disc reflects their ideal partnership, two artists of great sensitivity collaborating in performances that feature constant interplay of parts, alertness to each other's work, and superb playing as individuals. The Concerto for Two Pianos ripples along without a care in the world, just as it should, and the English Chamber Orchestra doesn't seem to care that nobody is conducting it. The pieces without orchestra are a bit less significant (as is the Concerto for Three Pianos), but the playing is so beautiful you won't care.

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.

Dame Kiri Te Kanawa's magnificent soprano breathes a fresh spirit into operatic favorites by Mozart, Puccini and Wagner in this collection of arias and other songs. Per Piate, Ben Mio, O Mio Bambino Caro and Vissi D'Arte are joined by Gustav Holst's In the Bleak Midwinter and the pop classic "The Windmills of Your Mind," among others. A diverse and exciting collection from one of the finest voices of our age.

Wolfgang Amadeus Mozart, baptised as Johannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical era. Born in Salzburg, he showed prodigious ability from his earliest childhood. Already competent on keyboard and violin, he composed from the age of five and performed before European royalty. At 17, Mozart was engaged as a musician at the Salzburg court, but grew restless and traveled in search of a better position…

This is the most beautiful of Mozart playing, his last piano concerto given here by Emil Gilels with total clarity. This is a classic performance, memorably accompanied by the VPO and Böhm. Suffice it to say that Gilels sees everything and exaggerates nothing, that the performance has an Olympian authority and serenity, and that the Larghetto is one of the glories of the gramophone. He's joined by his daughter Elena in the Double Piano Concerto in E flat, and their physical relationship is mirrored in the quality, and the mutual understanding of the playing: both works receive marvellous interpretations. We think Emil plays first, Elena second, but could be quite wrong. The VPO under Karl Böhm is at its best; and so is the quality of recording, with a good stereo separation of the two solo parts, highly desirable in this work.

Every major conductor, and most not-so-major ones, comes around to recording Eine kleine Nachtmusik, but not so many do it as well as George Szell and the Cleveland Orchestra strings. And let’s face it, you won’t find a period-instrument ensemble that plays with anything like this level of polish. The fact is, Szell’s conception of Mozart was not terribly far from “period” sensibilities: restrained use of vibrato, incisive rhythms, crisp ensemble, lively tempos, but also a welcome degree of warmth to the sound and of course incredible ensemble discipline and some of the best players on the planet. And he had real period instruments, meaning performers who owned top quality old violins and bows, not inferior modern reproductions of them. The result is as lovely a performance of Mozart’s perennially delicious Serenade as we are ever likely to hear.

Hilary Hahn and Natalie Zhu prove they are an excellent duo team in their first recording together, featuring four of Mozart's sonatas for violin and piano. All dating from 1778 and later, Mozart treats the two instruments more equitably in these sonatas than in his earlier ones. Hahn and Zhu are technically flawless together. They match each other as closely as two different instruments can to achieve a true duet sound. Just as Hahn "digs" into her strings for extra friction in the opening of the Sonata in E minor, K. 304, Zhu aims for the same tone quality with her touch. The two use longer note values, enhanced by vibrato and pedal, to give the music a pretty sound. It's probably more than a Classical era purist would like, but this is by no means a Romantic interpretation. Their slow movements, particularly those of K. 376 and K. 526, have beautifully rounded, cantabile phrases. The Allegro con spirito of K. 301 has bright accents and intense diminuendos and crescendos, demonstrating that this music isn't all elegance and delicacy.
