for SATB (with divisions), S. and T. solos, and 10 players Commissioned by Merton College, Oxford, this hour-long work for soloists, choir, and 10 players is divided into seven movements, beginning with Palm Sunday. Jackson's setting takes material from each of the four Gospel narratives, interspersed with Latin hymns and English texts by poets associated with Merton College over the centuries including Edmund Blunden and T. S. Eliot. The vocal score includes a piano reduction for rehearsal purposes.

for SATB and organ Setting a section from The Blessed Virgin Compared to the Air we Breathe by Gerard Manley Hopkins, this Marian piece opens with an extended soprano passage, underpinned by soft yet characterful organ writing. Several hallmarks of Jackson's style are evident, including soaring, melismatic soprano lines, sonorous harmonies, and repeated organ motifs. The result is a captivating and emotive work for church and concert use.

for SATB (with divisions) and soprano saxophone Setting the original Latin text of the hymn better known as 'Hark! a thrilling voice is sounding', Jackson creates an Advent piece of beautiful stillness. The largely homophonic choral parts, with a soloist supplying a gentle contrapuntal line, are contrasted with light and graceful interjections from the saxophone. The result is a quietly moving piece ideally suited for a reflective moment during an Advent service.

for SATB, percussion, and cello A work on the subject of pilgrimages to Santiago de Compostela, To the Field of Stars features a variety of texts on the nature of travel and worship. Underpinned by evocative cello and percussion lines, Jackson's strong choral writing offers fragments of spoken lines and unexpected melodic twists, while a refrain recurs in a new musical guise after each movement. The piece reaches its climax in the sixth movement when quiet, freely repeated choral notes ring out against cello and crotales, creating a musical 'field of stars'. Mysterious and beautiful, this...

for SSAATTBB Ave gloriosa Mater salvatoris is a challenging and yet delicate anthem, with subtle key-signatures changes, vocal divisions in up to eight parts, and alternating homophonic and polyphonic passages. The text includes excerpts from the synonymous medieval hymn and Wordsworth's poem The Virgin, making the piece suitable for a variety of sacred celebrations and particularly those of the Blessed Virgin Mary.

for SATB and organ Written for the 20th Anniversary of Norwich Cathedral Girls' Choir, this setting of the well-known All Saints Day text juxtaposes flowing melodic lines in the sopranos with rich homophonic passages, each bringing the text to the fore. The organ plays a prominent role, providing gentle undulating accompaniment, as well as fanfare-like exclamations.

for SATB unaccompanied In this unaccompanied setting of a text by contemporary poet Thomas A. Clark, Jackson skilfully evokes the magical atmosphere of the onset of nightfall. This is a striking and complex piece, with highly imaginative word setting.

for SATB with divisions, unaccompanied This setting of texts from Cymbeline and The Merchant of Venice, and Sonnet 98, is characterised by inventive textures and vibrant word-setting. The harmonic language is for the most part diatonic, but never plain, and there are some pungent dissonances, as the contrasts between and within the texts are laid bare in music of evocative power.

for SATB unaccompanied (with divisions) Three prayers, with a vision of light sets early Christian texts by St Augustine of Hippo, Baldwin of Forde, and St Mary Magdalene de Pazzi alongside words by Estonian poet Doris Kareva. Each movement offers a change of mood, from the reflective 'Conversi ad Dominum' to the more urgent and pleading 'Aufer a me, Domine' and serene 'Veni, Sancte Spiritus', with 'He who lives in light' offering an expressive and contrasting central movement.
