Gramophone Classical Music Awards 2014 Choral category winner! Purely on grounds of performance alone, this is one of the finest Mozart Requiems of recent years. John Butt brings to Mozart the microscopic care and musicological acumen that have made his Bach and Handel recordings so thought-provoking and satisfying.

The Sixteen, bright stars of the Baroque, have plenty to say on 20th-century repertoire (witness their excellent Britten series on Collins). Underpin them with the BBC Philharmonic and it might seem a magic formula. Ives’s unearthly The Unanswered Question holds few problems for instrumental players weaned on Maxwell Davies – no more than do the brilliant wind roulades of Stravinsky’s Symphony of Psalms. Deft BBC teamwork and a chamber articulation to woodwind and brass helps this Koussevitzky-commissioned masterpiece to shed its often hammy ‘big band’ sound, creeping closer to the subtle, leaner sonorities of his later choral works. It gains. The singing varies. Too many dynamic shifts sound prosaic or under-prepared; fortes are forced, with muddy results. The vocal blend (happier in lower voices) can seem haphazard and colours the Tippett, where the men’s roars – contrast the lovely, sensual soprano solo – seem crude. Get this disc, instead, for the rare, late Poulenc – his New York-commissioned Sept répons. It is a curiously under-recorded devotional work, bleeding with pathos yet pumping energy, its exoticism enhanced by slightly breathy, tender solos, and scintillatingly sung with just those crucial missing qualities of awe and freshness. A million times more refined than what goes before.

As a composer of sacred music, Bob Chilcott has found his own niche by writing accessible choral works that speak to contemporary sensibilities. As has been noted frequently, his Requiem evokes Gabriel Fauré and Maurice Duruflé, mostly through its gentle feeling and serene melodies, though without imitating their style or content. Rather, it has its own mix of somber harmonies and fluid, chantlike lines, and the expression of the work is a little cooler and darker. Chilcott's music admits occasional and mild dissonance, though the orientation is strongly modal and the harmonies always feel like a natural result of the counterpoint. Chilcott's Salisbury Motets, Downing Service, and three shorter pieces share the same modern Anglican style, which is approachable and easy to follow. The Wells Cathedral Choir, under the direction of Matthew Owens, sings with a pure tone and clear diction, and the sound of the recordings is quite resonant, thanks to the responsive acoustics of the Cathedral of St. Andrew.

Between 1961 and 1986, Herbert von Karajan made three recordings of the Mozart Requiem for Deutsche Grammophon, with little change in his conception of the piece over the years. This recording, from 1975, is, on balance, the best of them. The approach is Romantic, broad, and sustained, marked by a thoroughly homogenized blend of chorus and orchestra, a remarkable richness of tone, striking power, and an almost marmoreal polish. Karajan viewed the Requiem as idealized church music rather than a confessional statement awash in operatic expressiveness. In this account, the orchestra is paramount, followed in importance by the chorus, then the soloists. Not surprisingly, the singing of the solo quartet sounds somewhat reined-in, especially considering these singers' pedigrees. By contrast, the Vienna Singverein, always Karajan's favorite chorus, sings with a huge dynamic range and great intensity, though with an emotional detachment nonetheless. Perfection, if not passion or poignancy, is the watchword. The Berlin orchestra plays majestically, and the sound is pleasingly vivid.

Three of Szymanowski’s most important works show Rattle’s ability to energise music in which he believes. Sensuality and cogency blend in refined sound.

This recording has a huge advantage over most of its rivals for the attention of Tallis listeners: the wonderful acoustics of Winchester Cathedral. In this magnificent space, the soaring lines and resplendent harmonies of Tallis's greatest masterpieces find sympathetic resonance, resulting in a heightened dramatic presence that takes the music beyond earthly confines. Of course, beyond the exceptional quality of the writing, credit must go to the phenomenal men and boys of Winchester Cathedral Choir. Where, even in England, does one find trebles who sing with more assuredness, musicality, and beauty of tone? With a repertoire including "In ieiunio et fletu," "Salvator mundi," "In manus tuas," "The Lamentations of Jeremiah," "O nata lux," and the unbelievable 40-part motet "Spem in alium," this is the Tallis disc to own if you're buying only one.

Stile Antico's 2015 release on Harmonia Mundi, A Wondrous Mystery, is a sublime collection of Renaissance choral music for Christmas, presented in a pleasant mix of familiar German carols and a mass, with tracks interspersed for the sake of variety. This makes sense in consideration of the group's broad audience, which may know such popular hymns as Michael Praetorius' Ein Kind geborn in Bethlehem and Es ist ein Ros entsprungen, or Johannes Eccard's Übers Gebirg Maria geht and Vom Himmel hoch, yet be somewhat at a loss with the motet and Missa Pastores quidnam vidistis by Jacobus Clemens non Papa, a composer beloved by early music specialists but not exactly a household name for lay listeners. However, the a cappella performances are consistently beautiful and soothing throughout, and the quietly joyous mood of the music fits the album's title perfectly. The 12-voice choir's blend is well-balanced and transparent, and the ambience of All Hallow's Church, Gospel Oak, London gives an ideal resonance for the group's small size and close miking.

Five centuries, seven languages, and six singers with 35 years of remarkable experience inform this rare collection of choral music. In the world-renowned King's Singers resplendent voices, ancient and modern choral music comes to life with all the blazing immediacy and timeliness of the gospel of the nativity. With 25 pieces of music–ranging from familiar works such as "Coventry Carol" to the obscure Tchaikovsky piece "The Crown of Roses"–the King's Singers move through this hallowed and festive set with the vocal mastery that only three-and-a-half decades of accomplished work together is capable of creating. A number of contemporary carols written in the last century by composers such as John McCabe, Philip Lawson, John Rutter, and others are balanced by pieces by Bach and a host of traditional works. Lawson's "You Are the New Day," performed with a string quartet, stands out as one of the more notable performances. Like most of their music throughout Christmas, it reminds listeners that the art of music often interprets divine aspects gladly realized here on Earth.

Founded in 1906, Les Petits Chanteurs à la Croix des Bois (Little Singers of the Wooden Cross) are renowned as one of the world's most established children's choirs. Founded by Paul Berthier and Pierre Martin, two students on vacation at l'Abbeye de Tamie, the Paris-based traveling choir broke tradition with its lack of affiliation to a particular parish or cathedral. Directed by Father Fernand Maillet, they soon developed an international presence thanks to performances at the Vatican and an appearance in the 1945 film La Cage aux Rossignols, and continued to remain active throughout the 20th century, with singer/songwriter Matthieu Chédid, Les Prêtres' Charles Troesch, and Olympic rowing champion Adrien Hardy among some of their famous former members. By its centenary year, which was celebrated by a France2 show featuring duets with the likes of Tina Arena, Lara Fabian, and Nolwenn Leroy, the choir school had developed into a full-time educational institution, combining regular studies with a global touring schedule.
