Both nationally and internationally acclaimed, Jackson has given recitals and concerts all over the world, and made numerous recordings of solo organ music and of choral music with the choir of York Minster.
Jackson's extensive output of sacred and secular music includes canticles, anthems, hymn tunes (including the widely sung "East Acklam"), organsonatas and other organ pieces such as "Diversion for Mixtures", two acclaimed monodramas - Daniel in Babylon and A Time of Fire, an overture, Brigantia, a concerto, a symphony, and solo songs. Jackson's creative output has continued since his retirement.
Jackson is also the author of a biography of his teacher, mentor and predecessor, Sir Edward Bairstow, entitled Blessed City: The Life and Works of Sir Edward C. Bairstow. His autobiography, Music For A Long While was published in 2013.
