Abbot Alan William Rees, O.S.B. (1 February 1941 – 2 October 2005)[1] was a Welsh Roman Catholic monk, organist, and composer of choral and organ music. From 1986-1993, Rees was abbot of Belmont Abbey, Herefordshire.
Rees was born in Morriston, near Swansea, to Hilda and John Rees. He attended both an Anglican church with his mother, and a Welsh baptist church with his father. He attended Dynefor Grammar School, and later studied music and education at University College Cardiff.
Rees began a musical career as organist and director of the choir at Cardiff Metropolitan Cathedral, where he worked from 1963 until 1968. He then began a novitiate at Belmont Abbey, became a monk four years later, and was ordained two years later. He directed the music there, and taught at the school. He became abbot of the abbey in 1986, a position he held until he resigned in 1993 due to the pressures of the role and his mental health.[2] He was the ninth person to hold the position.[3]
Rees died suddenly after a fall in 2005. The coroner recorded a death of suicide, as he likely jumped from a landing.[4] Rees had suffered from depression for much of his life, and attempted suicide the year before.
