Little is known about Léonin beyond the fact that he seems to have had a bent for composing erotic poetry. The somewhat unhelpfully named 'Anonymous IV', a monk from Bury St Edmunds, tells us of two 'masters'—Leoninus and Perotinus—who dominated the twelfth-century musical world. Both were reputedly based at Notre Dame in Paris, and Leoninus was responsible for the Magnus liber organi, the 'Big Book of organum' (an organum being a polyphonic setting of plainchant), which is widely regarded as the single greatest achievement in the development of early polyphony.

Herman Finkers releases new album Missa Sancti Georgii. Herman Finkers has rearranged and re-recorded his St. George Mass with Cappella Amsterdam, Holland Baroque, and Wishful Singing. Herman Finkers composed a Latin mass, the Missa In Honorem Sancti Georgii, or Saint George's Mass, on the occasion of his wedding blessing on 15 June 1990, still without a Credo.

Cappella Amsterdam and its artistic leader Daniel Reuss present their third Pentatone album with a recording of Alfred Schnittke’s Psalms of Repentance. Schnittke composed the piece in 1988 to commemorate the Christianisation of Russia, Ukraine and Belarus in 1988, and based it on anonymous Russian texts from the 16th century about guilt and repentance. It is one of the most impressive large-scale works for a cappella choir written in the twentieth century, setting intensely emotional texts to equally expressive music, and approaching centuries-old Orthodox musical traditions through the lens of late twentieth-century music. This recording uses the original manuscript, which differs in multiple ways from the published score, resulting in an interpretation that aims to be closer to the composer’s intentions.

Poulenc's Stabat Mater, which the composer described as, "a requiem without despair," was written in 1950 following the death of Christian Berard, a leading figure of 1940s Paris who designed the sets for Cocteau's films and plays. This masterly work, dedicated to the Virgin of Rocamadour, gives pride of place to the chorus and clearly shows its line of descent from the French motets of the age of Louis XIV. It is paired with the Sept Repons de Tenebres, Poulenc's last choral work. Although sacred in nature, it was written for a non-religious celebration, the opening of New York's Lincoln Center for the Performing Arts. This recording's superb cast features soprano Carolyn Sampson and the Estonian Philharmonic Symphony Orchestra led by Daniel Reuss.

Cappella Amsterdam and its artistic leader Daniel Reuss return to PENTATONE with a world-premiere recording of David Lang’s the writings. For this cycle, Lang has chosen five texts from the Old Testament tied to Jewish holidays. These writings share a universal appeal, a focus on what it means to be human. Lang’s austere and repetitive score makes a profound emotional impact, fully in line with the poetry of the subjects recited. This album comes with insightful programme notes by the composer, as well as an evocative analysis by his esteemed colleague Nico Muhly.

Cappella Amsterdam and its artistic leader Daniel Reuss make their PENTATONE debut with In Umbra Mortis. The album brings together Wolfgang Rihm’s contemporary Sieben Passions-Stücke and Passion-related motets by the Flemish 16th-century polyphonist Giaches de Wert, revealing unexpected kinship between two composers four centuries apart. By entwining the old and new, the listener is invited on a chromatic journey of astonishing beauty. Since its foundation in 1970, Cappella Amsterdam has shown an exceptional mastery of contemporary and early vocal music, with acclaimed excurses to Romantic repertoire as well. Daniel Reuss has been Artistic Leader of Cappella Amsterdam for over three decades now, and has worked with several renowned choirs and ensembles.
