The discovery of any "new" large-scale work by Berlioz is bound to kick up excitement in the music world. So it was in 1992 when the manuscript of the long-lost Solemn Mass, composed in 1824, when Berlioz was 20, was unearthed by a Belgian choirmaster in Antwerp. A scholarly edition was quickly prepared, and John Eliot Gardiner gave the first series of performances in five European cities in 1993. It is from one of those live performances, in London's Westminster Cathedral, that this world-premiere recording derives.

Hector Berlioz, France’s greatest Romantic composer, exemplifies the spirit of his age – yet his genius was also ahead of its time. Reflecting his colourful life, his music is astonishing for its originality and ambition, and for orchestration of groundbreaking brilliance. This, the first-ever complete Berlioz edition, comprises carefully selected recordings and even includes works completely new to the catalogue. The accompanying booklet, lavishly illustrated, contains a fascinating commentary from Berlioz biographer David Cairns, whose words bring the composer’s music still more vividly to life.

The Canadian contralto Marie-Nicole Lemieux, with the Orchestre Philharmonique de Monte-Carlo and its Artistic and Music Director Kazuki Yamada, interprets the now ‘traditional’ recorded pairing of two sumptuous, escapist French song cycles: Berlioz’s Les Nuits d’été and Ravel’s Shéhérazade. Complementing them both musically and thematically is a third, less frequently heard cycle by another great French composer, Camille Saint-Saëns: his Mélodies Persanes (Persian Songs). “From the first note to the last, Lemieux’s interpretation of the Berlioz was exemplary …” wrote Bachtrack when she performed Les Nuits d’été in Paris. “From the depths of her lower register to her shimmering high notes, she traced a supple trajectory through the work, phrasing with amplitude and missing no opportunity for word-painting.”

Throughout her fifty year career Barbara Hendricks has shown herself to be one of the greatest champions of French song. This has always held a special place in her repertory and in her heart, as have German lieder, Scandinavian and Spanish songs (not to mention jazz and blues); her musical world has no limits. For this new recording made in 2016, the Swedish soprano pays homage both to her singing teacher and mentor, the great American mezzo-soprano Jennie Tourel, and to the creative genius of Hector Berlioz. If the Nuits d’été have long formed part of her repertory, the two cantatas Herminie and Cléopâtre are new.

Das Sommernachtskonzert der Wiener Philharmoniker ist jedes Jahr eines der meistbesuchten Klassikkonzerte überhaupt, denn es findet im festlich illuminierten Schlosspark von Schloss Schönbrunn in Wien vor 100.000 Besuchern statt.

Sir John Eliot Gardiner conducts the Monteverdi Choir, Choeur du Théâtre du Châtelet and Orchestre Revolutionnaire et Romantique in a landmark recording of Berlioz's towering opera. A tragic tale of love and fate, war and peace and the intertwined destinies of two cities, the opera is based on Virgil's imperial vision of the founding myth of Rome. The American tenor Gregory Kunde as Aeneas and the Italian soprano Anna Caterina Antonacci lead an international cast in this stunning production.

Another feather in the Dutoit/Montreal/Decca cap, not least for the sound engineers' achievement in so brilliantly capturing the mammoth sonorities of the Symphonie funebre et triomphale (whose first performance Berlioz conducted walking backwards at the head of his huge wind-and-percussion band, though—alas for the legend!—with a baton, not a sword). For concert hall, rather than open air performance he later added strings and a chorus, and it is this version that is adopted here (as it was in Colin Davis's 1969 Philips recording). Splendid as that issue was, this new one even surpasses it in clarity and impact, with its majestic brass chords and a chorus that adds incisively to the final climax.

Kiri Te Kanawa does well by these songs, avoiding the billowing excesses of sentiment that in other hands (or vocal chords) can make them sound much too soggy. Although Berlioz gathered them all together under the present title, all of the songs were composed at different times for different singers, so they aren't really a cycle at all. I seldom listen to all of them at once, and you should feel free to take them in any order that suits you. "The Death of Cleopatra" is an early cantata that perfectly suits Jessye Norman's stately delivery. She's always at her best playing royalty, and if they're dying in mortal agony, so much the better.

The first pleasant surprise here is the brightness and clarity of the radio broadcast sound; indeed, it is a bit too bright and harsh but better that than muddiness. There is evidently an audience who applaud at the end but otherwise there is no extraneous noise throughout. Secondly, there is the spring and bounce of the English Chamber Orchestra, alertly directed by Baroque specialist Sir Anthony Lewis. Thirdly we hear a first rate cast of splendid voices headed by Janet Baker, an array of voices unequalled in any of the other nine extant recordings.

This is a delightful recording from a conductor more closely allied than any other to Berlioz's music. With Berlioz the devil is always in the detail; he was an extraordinary orchestrator and capable of writing unidiomatically for instruments–especially the woodwinds–in order to get exactly the sound he wanted. Or rather, sounds, for the whole texture is made up of many layers. Davis understands this as if by instinct, and draws some beautiful playing from the instrumentalists without ever losing sight of the whole picture. It has been said that the French style of phrasing is all foreplay and no climax: the singers bring this teasing quality to their long, flowing lines but with a charmingly English home-counties blush too. Elsie Moris's light tone is a perfect match for Peter Pears' cool, silvery voice in this respect - and the choir too makes a good full sound without ever getting too heavy. The two discs also include some other gems from the pen of this most idiosyncratic of composers.

Gardiner here follows up his previous Philips Berlioz recordings with the Orchestre Revolutionnaire et Romantique – the Symphonie fantastique (6/93) and the rediscovered Messe solennelle (4/94) – with a searingly dramatic account of the later programme symphony, Harold in Italy. If anything this performance is even more biting in its impact, with textures transparent yet with plenty of weight, not least in the heavy brass. In a commentary on Berlioz and the conductor – shown recently on television – Gardiner puts as the first two of the conductor’s functions “to set the emotional temperature of the piece” and “to indicate the kaleidoscopic changes of mood that so characterize the music of Berlioz”.

The gleaming smile in the cover shot belongs to a young mezzo-soprano coasting at the top of her game, thrilled at the chance to show off in the 400-year-old Teatro Olimpico in Vicenze. The cheers interspersed throughout this June 1998 concert are her adoring fellow Italians. Count yourself lucky to be able to join them and Cecilia Bartoli with a recording that faithfully reflects the scrumptious range of both her voice and emotional dynamics.

This disc demonstrates that Cecilia Bartoli is as much at home in the world of the salon recital as she is in the swoops and vocal acrobatics of the Rossini coloratura repertoire. Her voice is in fine form here- -rich, resonant and full of surprising colours–but her talent for characterisation is even finer. In Pauline Viardot's "Havanaise" for example, she perfectly captures the flirtatious, almost desperate pleadings of a Spanish sailor for a French girl to accompany him on his boat –and then switches easily to the more capricious and teasing reply of the girl in French. In a number by Ravel (sung in Yiddish and Hebrew) she brings a rather elliptical exchange between a father and his young son to life with exquisite tenderness, and finds yet another voice out of her repertoire to characterise the little boy.
