Gregorio Allegri- Missa Vidi Turbam Magnam

Gregorio Allegri (1582 -- 17 February 1652) was an Italian composer of the Roman School and brother of Domenico Allegri; he was also a priest and a singer. He lived mainly in Rome, where he would later die. He studied music as a puer (boy chorister) at San Luigi dei Francesi, under the maestro di capella Giovanni Bernardino Nanino, brother of Giovanni Maria Nanino. Being intended for the Church, he obtained a benefice in the cathedral of Fermo. Here he composed a large number of motets and other sacred music, which, being brought to the notice of Pope Urban VIII, obtained for him an appointment in the choir of the Sistine Chapel at Rome with the contralto role. He held this from 6 December 1629 until his death.
