Formed by their conductor, Peter Leech, in 2009, principally for the performance of late Renaissance and Baroque choral works, as well as contemporary choral music, Harmonia Sacra has gone from strength to strength with critically acclaimed performances in widespread UK venues such as St George's, Bristol, Wells Cathedral, Christ Church Cathedral, Oxford, St Mary Redcliffe, Bristol and All Saints, Oystermouth. Described by the Bristol Evening Post as 'a fine body of singers' the choir is well known in Bristol for its ever popular annual Advent Reflections concert at the church of St Thomas the Martyr, and has released three CDs on the Nimbus Alliance label, the first two, Cherubim and Seraphim and Princely Splendour, having received rave reviews from prominent critics at Classical Net, MusicWeb International and elsewhere. The third CD, Lux Memoriaque, was released on the Nimbus Alliance label in October 2017, featuring mostly first recordings of contemporary choral works by Robert Hugill, David Bednall, Jonathan Lee, Lawrence Whitehead and Peter Leech. In 2015 the choir collaborated with Cappella Fede for a landmark Toccata Classics CD, The Cardinal King (released in 2016), featuring first recordings of choral music composed for Cardinal Henry Benedict Stuart (1725 -1807), which has received estatic reviews in numerous online music magazines, as well as BBC Radio 3 Record Review. In September 2017 Harmonia Sacra undertook a tour to Rome, where they gave concerts in S Lorenzo in Damaso, and SS Dodici Apostoli, featuring the first modern performances of sublime choral works by eighteenth-century Roman composers originally performed in those churches but forgotten for over 200 years. The choir's performance at the Capitular Mass in St Peter's Basilica was highly praised by Tarcisio Cola (Prefect of the Cappella Giulia) as one of the finest guest choral performances in St Peter's in recent years.
