Messe solennelle is a setting of the Catholic Solemn Mass by the French composer Hector Berlioz. It was written in 1824, when the composer was twenty, and first performed at the church of Saint-Roch, Paris on July 25, 1825, and again at the church of Saint-Eustache in 1827. After this, Berlioz claimed to have destroyed the entire score except for one movement (the Resurrexit). However, in 1992 a Belgian schoolteacher, Frans Moors, came across a copy of the work in an organ gallery in Antwerp. The first modern performance was given by the conductor John Eliot Gardiner at the church of St. Petri in Bremen on 3 October 1993 and the first world recording was made by conductor Jean-Paul Penin, on 5 October 1993 in the Vézelay Basilica.
