This production of Mozart's Le Nozze di Figaro caused a sensation when it first came out, stunning critics and audiences alike with its perfect balance of joyous humor, improvisatory brilliance, and always subtle music-making.

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.

Were just one example to be given of the richness and diversity of Mozart's achievements, Concertos Nos. 23 & 24 would undoubtedly make excellent candidates. Completed almost simultaneously in Vienna in early 1786, the two concertos contrast starkly and seem to have been written years apart – or by two distinct yet connected minds of equal genius. Even more astonishing is the fact that they were written in parallel with the first masterpiece of the Da Ponte trilogy, The Marriage of Figaro, while sharing with it very few stylistic similarities.

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.

Praised by Gramophone as ‘one of the more original thinkers of his generation’, the Italian pianist Federico Colli is internationally recognised for his highly imaginative and philosophical interpretations and impeccable technique. This album is the first instalment of a new, intensely personal project for the pianist: an exploration of selected piano works by Mozart. It was the discovery (at the age of around six) of Mozart’s music that caught the imagination of the young Federico and inspired him to study music, and it was winning the International Piano Competition Mozart, in Salzburg, that launched his career as a pianist. His approach has been to immerse himself completely in Mozart’s own experience at the composition of each piece: where was Mozart living, what was he doing, what were his motivations behind each composition? Only after in-depth study of biographies of Mozart, his (and others’) letters, the historical, social, and political background, the Zeitgeist, the cultural atmosphere surrounding each work, does Colli then approach the scores and start the process of building his interpretations.

This stylish and beautifully sung and acted 2006 performance of Don Giovanni from the Zurich Opera House should be of strong interest to anyone who loves the opera. The production, directed by Sven-Eric Bechtolf with costumes by Marianne Glittenberg and particularly striking sets by Rolf Glittenberg, is visually and dramatically dazzling. The timeframe is contemporary, but the clever trompe l'oeil set suggests the infinitely receding stage depth that flourished in 18th century scenic design. Don Giovanni's palace is a cosmopolitan playboy's penthouse, and the costumes clearly define the social standing of the characters in modern terms.

On this recording of The Seven Words, the Rosamunde String Quartet offers a compelling rendition of one of Haydn's most complex compositions. The Seven Words was originally composed for a full orchestra as a series of seven adagios, which were meant to be interludes during a congregation's meditations on the last seven words of Christ on the Cross. Haydn struggled with a way to compose seven connected pieces of music that were solemn and yet varied enough to keep the listener from getting bored. The members of the Rosamunde Quartet are technically brilliant as they demonstrate the composer's solutions to this musical puzzle. Even though the tempo is slow, they never let the music become ponderous or oppressive. But to Haydn, The Seven Words was more than just an aural conundrum. He felt the composition was perhaps his most sacred work, and the quartet plays this music with reverence for the composer's spiritual intentions. This is a profound piece of music, and the Rosamunde does it justice on each of its many levels.

No one did more to combine in his operas the innovations of the Viennese classical composers, Haydn, Mozart and Beethoven, with the Italian ideal of bel canto than Johann Simon Mayr, the Bavarian composer who rose to fame in Italy. His opera Saffo, first performed in 1794, dates from his years in Venice. Not only was it his first opera but it was premièred at the Teatro La Fenice where it was enthusiastically received. It is full of surprising and striking elements, with a strong musical realisation of the text, supportive string and woodwind writing and vivid solo and choral effects. Set by the Rock of Leucas, from which unsuccessful lovers leap to their deaths, the opera deals with the poetess Sappho’s unhappy love for Phaon, finally resolved in a happy ending.

While Carl Philipp Emanuel Bach was above all else a dazzlingly accomplished harpsichordist, his considerable output for flute can easily be explained by the milieu in which he worked for nearly thirty years. The Berlin court of Frederick II was in fact governed by two flautists: the king himself, and his teacher and accredited and exclusive composer, the famous Johann Joachim Quantz. His five flute concertos were derived from a group of seven concertos for harpsichord written between 1747 and 1755. It is very likely that Emanuel Bach himself made all these transcriptions. The versions for flute nearly always date from the same year as the corresponding harpsichord concerto, which suggests virtually simultaneous conceptions.

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.

The Beethoven Triple Concerto is a strange work, with the most important–-or at least prominent–-solos given to the cello; it is the instrument which introduces each movement. The remarkable Martha Argerich wisely allows Mischa Maisky to shine in his solos and leading position, but her contribution is anything but back seat. Her customary virtuosity is everywhere in evidence, and, in a way, she turns the piano into the spinal column of the work, with the violin and cello playing around her. Every time Maisky is about to lapse into a mannerism which might detract–-too much sliding, a dynamic slightly exaggerated–-Argerich brings him back, and both of them play with handsome tone. Capucon's violin is recorded a bit stridently (this was taped live in Lugano), but his playing is equally stunning. Alexandre Rabinovitch-Barakovsky leads the orchestra matter-of-factly until the final movement, when he catches the proper fire. In the Schumann A minor concerto Argerich is wonderful the solo passages and a fine partner in orchestrated ones and she really makes much of both the lyrical runs and the dance-like passages in the last movement. Recommended.

Isabelle Faust and Alexander Melnikov present the third volume in their complete set of sonatas on period instruments. Their playing, showing “great elegance and utter rigour,” is distinguished by “a tender and delicate expressiveness served by exceptionally subtle nuances” (Classica).

Why, in a booklet accompanying a recording of "Flute Music at the Court of Frederick the Great", is an attempt being made at this point to take a look into the soul of a damaged monarch? There is a guiding "thread of Ariadne" that leads through the labyrinthine trials and tribulations of Frederick's life and suffering – a singular passion that he discovered at a young age and never forgot throughout his life. It is the love of music, especially the love of playing the "flûte traversière".
